The last minute nerfs were to account for a bug in their sims...imo they didn't have enough time to thoroughly vet the spec going into live...and, thanks to Blizzard's "wait and see" mentality on buffs/nerfs, WW gets to spend an entire tier being sub-par DPS. The nerfs had nothing to do with SEF. SEF would have been awesome...last tier. On a few fights.I will be happy if monks finally get buffed back up, it's been sucking raiding as WW, I actually went and leveled my rogue finally from 85-90 because I was sick of crappy DPS compared to before...seriously, getting a worthless ability like SEF, no matter how cool it looks, was not worth the nerfs to single target at all...
There are a lot of inconsistencies in stat weights right now, there's some people out there favoring Mastery who really shouldn't be.
WW damage is decent right now if you know what you're doing, and buffs on the way. What we need is utility. Until then, we will live under the shadow of our Brewmaster/Mistweaver fellows.
