Dreadlord- AoE, great aura, sleep is very annoying especially if you do on casters, heros, and ultimate is truely an "ultimate"

Death Knight- Death coil number 1 move in WC3, aura really aids goyles, and ghouls, and ultimate will change tide in any battle.

Warden- ONLY NE HERO, that has AoE and GOOD aoe, avatar is more godly than metamorphesis, blink is a hero saver, and shes just untouchable branded unfuckable
