we have 10hrs + attempts on him, seems like everyone his having trouble with the force lightning. has anyone else experienced where he bubbles himself and keeps killing the group?
You spent 10 HOURS on Revan HM? That is completely absurd.
It's not that hard. Get your interrupt sorted, get your tank to use defensive CDs at the right time, have your healer dps, and blast away.
Revan HM is farmable.
