It's impossible without 5 by design, you cannot get to the end without 5 people it's deliberately made to be physically impossible to do it. As for the fight itself, this is a map where you want everyone to be a hybrid with self-healing or at the very least any kind of solid builds with solid self-healing, so I wouldn't recommend most AT's. The main reason I disliked AT's, cause I know they'd spend all day dead in the therakiel fight since he has an attack that always hits everyone in the room, you need to block it. Self-healing is needed to survive the same attack repeatedly, but it's not broken like the frosticus nukes and it's very blockable compared to even a blue sphere from gravitar.
It's a fairly balanced battle, but it's made for the pre-free for all days.
