Run LI with columi is not overgearing it, thus the boss should drop something better than it.
Run EC HM with BH/Campaign is overgearing it ? Seriously, I'm getting tired of hearing you. you are bad enough to wipe on LI, even in BH/Campaign, and you don't even understand that goodplayers can do it in Tionese, and you must overgearing it, then whine about hw yo don't get stuff for the achievement.
Good players can do it in Tionese.
Decent players can do it in Columi.
Bad players need more.
Same story for EC HM/NiM and Asation HM. Do you know that EC HM can be done with Rakata without augments ?
