You really have no clue how to play this game.
Barb got a whole bunch of Flay buffs. Flay is a strong skill that stacks millions of bleed damage so Rupture can explode for billions of damage. And it gets buffs. Why? Because everyone is using Bash (duh), so of course Flay must be underperforming, so we must buff it. (Blizzard Logic?)
Meanwhile Sorc can’t even get any buffs to any skills other than a tiny Incinerate DR buff, and gets crappy buffs to Combustion instead, oh wow now instead of 2% extra damage we get 4% extra damage! Whee!!!
You should stop posting, you have no clue what’s going on in this game.
