If by that you mean pumping cray numbers, necro ain't ever gon' do that. Or provide much in the way of group utility. Necro dps is
one of the lowest in the game.
Still, if you wanna max it, 66002 dagger focus warhorn did indeed change my playstyle considerably. Quite sad to load up on zerk, pop enpower, drop a well, some marks, hit DS and see crap melt around you far faster than it ever did on a pure condi build, but oh well, it is what it is. Survivability isn`t really a concern since that is one area where we're really good.
But really, play whatever is fun. I still had plenty of fun with condi/marks and it was supah great in the wubs (provided i didnt have to damage strutctures >__>). Still keep condi set around for that.
