Dang, I must really suck
Had several goes at Esseles yesterday with my Jedi Guardian (level 11). Never managed to get past Ironfist. And that was with a full group (2x10 and 2x11).
Guess I'll have another go (or more) at it today...
I as a consular tank (as much sa a lvl 11 consular can be called a tank lol) and a Jedi Sentinel friend, would have 2 manned the whole instance easily if it wasn't for Ironfist. We had him down to less than 10% twice, but eventually went back when we were both 14 and 2 manned it. 4 players over level 10 should be able to beat ironfist, and the rest of the instance is trivial anyway.
