So let me ask, are Sorcerers unstoppable grinding machines and everyone else is left in the dust? This video seems unreal, watching him run into a pack of 15 mobs and sit at near full life the whole time while he is AoE'ing stuff down in 4 hits. And it all hinges on one Sorcerer Class ability; Critical Surge. At max rank, it increases your damage done and critical hits heal you for 65% of damage done. Wow.
I havent found anything similar at all in any trees or lines anywhere in the game. It seems game breaking to me. Thoughts or feedback? I realize Nightblade Siphoning tree has a little leeching, but its ability specific. This spell is really in a class of its own.
