Lately I’ve been finding myself having aggro issues with my DW spec, which has points in BCB rather than Subversion. People on EJ have been math-battling it out (no clear winner yet, it seems) but I’m finding myself leaning towards a Subversion build. While I don’t usually pull aggro, I find myself uncomfortably high on threat, to the point where I occassionally stop DPSing or Shadowmeld to avoid death by one-shot.
Since Subversion obviously provides its own boost to damage (unfortunately harder to quantify than BCB, which shows up in parses and so is more easily valued) as well as some nice utility, I think it might just be superior. However, not all tanks being equal, this talent swap should be considered on a strict case by case basis. If your tank is always far above you in threat, BCB is probably a better bet for you. If not (and some fights are extremely threat sensitive, such as Vezax, who is untauntable), seriously think about using Subversion instead of BCB.
On a side note, I’m going away from Monday to Wednesday night and won’t have access to my laptop, so this is the last you’ll hear from me (except perhaps a few tweets from my phone) until I get back. If you have a question or simply want to tell me something, I’ll most likely still have access to e-mail. Have a good first half of the week, interwebs.
