Why exactly? It's true I made my warlock because of that talent, but how am I exactly influencing your experience in WoW by having a warlock myself? Just curious.
Blizzard are in a pickle imo. They want to change KJC, but any change they do will be a step back for the class and yet they refuse to look at the other caster classes and their mobility and maybe improve things a bit where they are due (looking at arcane).
