From a PVP perspective:
Aren't rogues ment to be a disrupting ninja from the shadows?
Who can lockdown their target, disable another and deal dmg in the same time?
With any new design it would be awesome to get rewarded by harassing multiple players/target's, one after the other.
That way we build up combo points and dump the combo points with a special move.
Note that I just wrote *special move* instead of *Finishing move*.
Most of the time we aren't finishing anything anyway...or are we finishing a combo (*Finishing Combo -ability-*?)
Maybe include a time limit in which you get rewarded by getting certain combo's.
Took too long to combo? Start/try again (I failed, I must restealth/vanish).
Combo Points on the player rather on the target could be fun and unique this way.
However, rogues are still and will be an awesome class regardless of any changes.
The mechanics work, I've never felt handicapped.
