During fights it is imperative to know when your opponent will attack and what attack they will use, most skills have lead-ups that tell you this. Unfortunately stealth takes this fairness away which is awesome for those in stealth, that's less play skill they need to win. But for their opponents it's very unfair, add to that the ability to attack from range while under stealth it becomes merely a matter of waiting to wp after death. What would be fair is that in order to attack or stake a downed you must come out of stealth first, and if hit you drop from stealth. I believe stealth was intended as an evasive action or to set up positioning, not as a "ha-ha, you suck cause you cant see me" action.
