Mmhh, what if KJC is redesigned with a small DPS loss penalty when the caster moves?
Or a ligher casting speed penalty (like at the beginning, not as punishing, tho).
Point is, as of now, the talent has the same chances to either get nerfed, overhauled or stay untouched.
Devs know already, they made the mistake of KJC with just the speed penalty, then they balanced affliction and destro around it (was obvious they did). Now they can't go back with just scrapping away the talent without (imho) strong DPS compensation.
Giving fillers the chance to cast on move, it works for destruction, but not for affliction. Allowing MG to be cast on the move is as much as not nerfing KJC at all.
Oh well, i play demonology, i don't really care about that talent anyway :X
