Warlock is better than a necromancer in every way. Corpse explode may beat out death sigil but not by much.
Warlock summoner is like 100x faster than a necro summoner.
ES Warlock is like 10x better than a bone spear necro.
I could play a javazon, but then again.. ES Warlock exists and I dont need to make an infinity.
Sorcs are nice for free teleport, but warlocks are so strong you can get so much gold find a tele staff doesn't even break the bank.
Assassin traps are strong and dual element allowing you to farm everywhere, but demons and bloodboil are better AoE and faster to deploy.
Druids fire skills aren't as good as Warlock, and druids summons... lol. Melee Druid seems pretty strong, but ES warlock is ranged which is almost always better.
Paladin!!! Yea but Warlock has AoE magic spells and doesn't need to stand near stuff with awkward hammers. Also you get a demon on top of it. Smiters are strong, but ES warlock can do Ubers at distance with a demon tank.
