I have a feeling that the devs are working on balancing the epics a bit this month. It's been a while, and they have stated that they aren't doing any more major class balancing.
So, now would be a good time to talk about whether our Epic weapon, (fabled and mythical) still needs work. I started a thread on the official forums about Possess with respect to raiding, since some folks have suggested putting no concentration for that spell on the mythical. However I don't feel qualified to talk too much about mythical abilities since I have yet to obtain mine. (Stuck on Druusk and Nexona mostly because we can't get a full raid force of keyed folks to all show up on the same day.... sigh.)
As to the fabled epic: The proc might as well not be there, but the reuse is nice. I think they need to put a useful proc on it. A nice defensive or offensive buff, perhaps or, since we are a debuffing class lately, a nice debuff proc which stacks well with other debuffs would be great. (Some new debuff, even!)
I think no concentration on Possess is a bad idea, which I outlined here: (
Possess Essence in raids (Mythicals?)).
Though I could see a nice upgrade to Impetus being welcome instead of the fighter taunt thing. (Group-wide plus some bonus similar to rapidity.) Group manaflow sounds pretty much awesome the way it is now.
