I like Onyxia as much as the next old-school raider, but this feels really lazy. In the wake of a raid instance with one room and some bosses, why is Blizzard resurrecting old raid bosses again? First there was an updated (and severely dumbed down) Naxx, and now a dragon whose head has hung in Stormwind, whose storyline is pretty much done?
Blue poster Zarhym has claimed that the mechanics will be updated to fit with “modern” raiding. The problem with this, whether or not the encounter turns out to be fun and challenging, is that there is no need for another semi-connected one-boss instance in WotLK. We’ve already had Malygos and Sartharion (and Ulduar, which was equally disconnected from Arthas and co.). If they are going to introduce more bosses, I want them to be undead – something that the Lich King throws at us to show he’s still actually around.
So Blizzard: enough recycling content. There’s plenty of interesting material going on that’s actually in Northrend and hasn’t been done to death (literally) already, so tap into that stuff and leave Onyxia where she belongs – in the grave. (I know it’s too late for this wish, but ranting is better than nothing.)
