Yes, sir, you are right about the fact that the necro is a great class and you can make VIABLE builds around most skills ? Oh cmon, reaper and Aether Death knight are past the point of viable tweaked or not. Reaper breezes through content. Give them a chance. this is far from some pre expac druid viable type situation. You made your opinion on vitality caster and they are slow, especially without end game gear mods. Most things vitality are slow, except maybe a very good pet build
P.S.: Don’t judge pet builds with what you see on this forum. Yes I’ve learned, especially after talking to Dashiv, that late game pet builds require thinking well beyond the obvious.
