Edit: Blood Elf with bloodthistle on(always), of course..
wow.. just wow.
by definition undead do more damage. but overall, Belf AoE blanket silence makes belf > undead
i would say blood elf would have much more relevant damage, the extra ticks from touch of the grave does not compare to the blanket silence effectiveness, especially with the reduced cooldown
Hashbrowns Thank you, you QT!
By the looks of this beautiful sheet http://i.imgur.com/2tHPCdx.png(Credit to Bend) Blood elves basically have a more intellect basis than undeads, which means Blood Elf is superior , in DPS/Healing matters. Every class has its own situation benefits.
granted its very minor.
looks>being bis, roll undead
