According to talk going around, and my own math from what I've seen from pre patch to post patch, Frost received a ninja buff as well.
Apparantly, a glyphed frostbolt previously kept the 3% damage tax for being a snare. Post patch, this tax has been changed to a small % of crit chance (possible for all snare attacks?).
This basically means that every frostbolt is (tentatively) 3% more powerful, and crits less.
Frost isn't a big deal to anyone but me (since I'm a moron that likes to go against the mold ^_^), but it gives me hope that more help is coming. With enough haste, 3% per frostbolt (mine run at around 1.9 seconds, under self haste buffs it's around 1.6, under self haste + heroism 1.2) turns out to be a lot of extra damage (3% damage boost every two seconds, so 1.5% DPS boost at my current haste level) which scales with gear.
Other than that, looks like Arcane is back in the game, but even more boring.
For my fire spec, do y'all think it's worth speccing back into Combustion now that it does something?
