They have done it in the past - but I don't think this is a SoO thing either, this is a single target WoD buff: and we are bottom of the meter before this, so it makes sense - it also buffs our mastery scaling - so CoP single target particularly should be more competitive, but AS/VEnt will remain sucky at single target. That's fine imo.
I was never worried about our damage though - I'm worried about how squishy we are, and how this is going to be a double melee or melee+hunter swamped season: we're going to get sat on while fmages are blinking around spamming roots still. Still Fmage superiority IMO. Armor down from 61% to 16%, and loss of VE as a defensive cooldown
Edit: Still fixing addons during raid, but I will test a spike/blast/insanity build on Malkorok.
