As you’ve probably noticed, in patch 4.0.1, Blizzard introduced what is essentially a default-UI version (WoW Insider gives a brief explanation of it here) of Power Auras, a mod that let you create large, visible notifications for procs, debuffs, any number of things. At first it was confusing–I didn’t know what meant what, and big things were popping up on my screen confusing me during combat. That quickly passed as I became familiar with new talents and abilities. And while the WoW Insider post I linked above says this about Bizzard’s auras:
It’s simple, it’s effective and it’s pretty. I was really impressed with these ability notifications because, frankly, there aren’t really any options. The system is just … there. Believe me, it’s a plus. Sure, there are options to turn it on or off and set the opacity, but that’s all you get. Fewer options, in this case, is better,
No countdown to be seen
I have to disagree that fewer options is better. The images are nice, yes, and it’s good that we can set the opacity, but frankly, that’s not better than Power Auras. This isn’t really a complaint, seeing as how this is the case with almost all basic UI elements that are inspired by addons–the Blizzard version is functional but not customizable. But rather a plea that raiders do not use these over Power Auras or similar notification systems.
Timing is everything
The most important feature that the Blizzard auras are missing is a timer. When Killing Machine or Rime procs (the two Frost DK auras), I need to know when they’re going to run out so I can plan my next few abilities appropriately. It’s also crucial to know what’s going on with other abilities. Again taking the example of Frost DKs, Unbreakable Armor, on a 1 minute CD, needs to be used often, and Power Auras will help while Blizzard’s won’t.
I haven’t yet had a lot of experience with the raid UI, but my guess from looking at the options is that it has about half the functionality of Grid. When I healed as a Druid, one of the most important uses of Grid was seeing where my buffs were and how long was left on them without having to click on players individually. Grid does this–admittedly with a fair amount of setup–and does it well.
Limited options
Too much is too much
On the opposite side of things, some default UI stuff just does way too much. Again, this comes down to a lack of customizability, but leads to a problem of too much information busying up your screen. The default Floating Combat Text is a great example of this. Realistically, you don’t need to see any kind of damage in a raid environment, but it is nice to see when you hit a big crit or something. It’s also really important to see certain things, like immunes, parries or misses since that can either mean you’re positioned wrong or have been standing in something bad (e.g. dust clouds). You don’t need to see your DoTs ticking, your pet’s attacks, other raiders’ hits, white hits, etc. I set my combat text to display the following:
- Any incoming damage above 3k (probably will raise this once Cataclysm raiding begins since health pools will be much larger)
- Outgoing damage above 5k (this means I don’t usually see non-crits or white hits)
- Parries, dodges, misses, immunes, buffs and debuffs
Can't control the flow of numbers
That’s the really important stuff you need to see. Blizzard’s combat text just isn’t this flexible. And your level of addon customization should ideally reflect how seriously you raid. If you do 5-mans and that’s it, well, most of this stuff won’t matter. But in a 10-minute long boss fight, it’s extremely important to see what matters most in a clear and understandable way. Lack of information or missing something in a cloud of text is no excuse for a death. So get customizing!
Like stats, raiding UIs should be min-maxed
For raiders, the barrier to entry is already steep. If you want to seriously play your class, there’s a lot of information you need to know, and more and more comes with each patch/expansion. 4.0.1, for instance, introduced entirely new abilities, a new rune system, more glyphs to work with and an easier way to switch glyphs around, and reforging. Addons are simply another aspect of this. Many great addons do far too much or far too little out of the box, such as MikScrollingBattleText, of which I use a very pared down version.
So when you’re going into your next raid, pay attention to exactly what you’re using the default UI for and how you could do it better with addons. No matter how much Blizzard incorporates addon-inspired ideas, these will almost never be ideal for any serious raider.
Runeforge Gossip 
I’m in an interesting place when it comes to UI customisation. I LOVE to tweak my UI, but at the same time I play on a little laptop that often can’t take the stress of a boatload of addons. So for me, it’s a balancing act that basically boils down to me only taking addons I ABSOLUTELY need.
For example, I absolutely need a rune watcher. I’ve tried Magic Runes, but am more fond of DKM, personally. I absolutely need some kind of raid frames, and I need DBM, in all its super-useful glory. But from there I get into an interesting middle ground. See, I PvP, and in PvP the goal is often less about doing the most possible dps, and more about managing to stay alive long enough to keep doing damage. In the arena finals every year, the best PvPers in the world perform using ONLY the default UI.
Which brings up questions like: Do I really *need* to have a unit frame besides the default one? My answer tends to be no. Do I need a special combat text mod besides the built in floating mod? I don’t, really. So I axe all the mods that aren’t absolutely necessary for me to perform, in order to save on those precious fps. Obviously, you’re in a different possition as a serious raider than I am as a PvPer. But I think it’s interesting to see how you can do without a ton of addons. In my case I’m actually so used to elements of the default UI, that I do better with it than I do with a third-party replacement.
Different strokes!
I actually think PvP requires more addons than PvE does. In PvE, you absolutely NEED some form of boss mod, raid frames, and something to deal with procs/runes/runic power.
In PvP (when I say PvP, I mean arenas, BGs are far less addon heavy), you need to know exactly what procs, abilities, cooldowns, etc. your opponents are using. You need enemy raid frames, not just your own raid frames. In 2v2, it’s necesssary to see what both opponents are casting. In 3v3, 5v5, etc.? I can’t even imagine. The default UI just doesn’t have all these features in a way that can be effectively maximized.
I’m really weird, to be honest. I’m perfectly happy with the new UI brought about by Blizzard (with DBM and Omen added in) I don’t need a lot of stuff, or a lot of flash. Now that I’ve thought about it for a while, I have realized that I never, ever, watch my runes or RP. I just *know* what I need to do next. Is that odd?
Alas. By the way, it’s nice to see another DK who knows what they are talking about. I actually don’t like Frosty that much; unholy is my favourite and has been since…forever ago. I’m hesitate to change. If it ain’t broke don’t fix it, etc, etc.
I don’t think it’s odd that you don’t watch your runes, because I have talked to many DKs who don’t. However, I do think not watching your runes negatively affects DPS. Without seeing what runes are on CD and when exactly they’re coming up, it is extremely difficult to know what ability to use next, especially now that you don’t need to USE ALL RUNES ALL THE TIME to avoid wasting regeneration time.
Maximizing rune regeneration rates (especially as Unholy, where you often get unexpected haste procs, is really important, and I don’t think you can effectively do this without watching your runes.
Re: Unholy v. Frost; I like both, but currently my raid group needs Frost’s buffs and not Unholy’s. So that’s where I’ll be.
