Say if team Red, is just slightly better than team Blue, and would win in a 2v2 encounter, but team blue had disabled team red and brought the perma health down, Blue could suicide while Red is respawning and bring themselves back to full, then team Red would win the 2v2 encounter AGAIN, and repeat, it give team Blue (the slightly not as good) team left with no progress on defeating Red. It's like a tool that could repair all of the perma, OP it would be nerfed!
