First room on the left is a tough room,the only mob in there that will summon is the named.Room can be tough to break but once cleared it can be kept cleared if you keep on top of it.
Best thing to do is try to snare or root one of the mobs on the right side and you get about 4 or 5 mobs inculdeing the medic or the fleshflayer whatever one is up at the time.Take them to zone line and root one or 2 and zone out then zone back in and they should still be there rooted,this way you dont have to deal with a lot at once.
This is very importain when getting rid of the medic since he will just heal any you try to beat down.When dealing with the medic take him to 50 percent and he will start to heal himself,keep him nuked and beatdown far below that and let him keep healing himself to just under 50,he will keep trying to heal himself instead of attacking you and will run out of mana then he will run.
Have fun and GL
