Honest question regarding SK races

[Khurak]

Ok i know i will end up playing what i want (not truely a min/max peep here).

However, Is it even worth it to play a DE vs an Ogre or Troll?
Is the additional mana going to be worth it in the end vs STR, STA, Slam (+ Stun Immunity or Regen) since Hide will be a skill for all.

Am i missing something in high level PvP? Besides the DE look cool factor ?

Thanks,
