THE KJC change is welcome. Sorry but the whole talent was a fail design from blizzard. Yeh its cool to cast and move but the 30% speed debuff was meh. Plus they balance all our dmg around the fact that we were casting the whole time. If its on use 1.5m and you get a 20 sec window when you can cast and move (no speed debuff) i think its a fair tradeoff, but they have to put it off the gcd to be worth it.
Affliction 4set bonus is completely crap. I dont really know whats in blizzards head atm regarding affliction. With the amount of haste that flies around shard generation is a joke. Affliction doesnt need more shards. What they should address for affliction is aoe. Afflicitons aoe is 1 button. Thats pretty fail. They should add 1 more mechanic or something to provide some snapburst aoe on top of seed.
