After some research I came to the conclusion that:
- Both can be cows
- Both can rdps, melee and heal
- Both are recommended to level with melee spec
- Both will have to heal in pve end-game
- Both have crappy mana inefficient rdps specs
So that leaves 2 questions:
1) stealth + brezz >< self-rezz + regular rezz
2) which rdps spec is most mana efficient of the two?
