I'm dying in almost all of the Belsavis Heroics, the problem is when I get attacked by 5 or more enemies, in Lights Out there's packs of 6-8 enemies and I died on each one. Getting attacked by 1 easy np, 2 fine, 3 okish, 4 tough, 5 hard, 6 Lana is dying.
Note: This is on my marauder who doesn't have much area damage so when attacked by a large pack of enemies if Lana gets targeted by all except the one I'm killing she almost dies or if I get targeted by all the enemies Lana can't keep up with the healing.
