Repair units prolong the game by a hell lot.
You can die trying to kill off an important suit of the other team, but a single healer unit can nulify all you efforts over a min or 2.
Other suits are banned purely because they are still broken as shit. In the end though, it's all down to what the room master decides on and not everyone has the same opinions on the suits.
