Ok so my main issue with the class at the moment is Vengence.
Main problems:
1. In some exp mode dungeons, killing mobs during Vengence that would normally give a rally while in a downed state will NOT let you rally. This is true even if you have the Sweet Revenge trait. The boss fight that comes to mind is Subject Alpha in CoE exp. Tendrils, small Asura mobs, and oozes do not give rally, when they should.
2. Vengence remains active after defeat. I cannot stress how aggravating it is when you immediately rez at a waypoint after being defeated while in Vengence to find yourself about to die AGAIN in a few seconds for no reason and to eat another dose of dura.
