Survival is not focused on PvP. If you want to do that go on a PvP gamemode. Survival is PvE. Neutral. Ya it's overpowered and unfair, but they paid $250.
It really doesn't help if you give me a response without any comment. May as well just click the X and not respond if you wont comment what the flaws are in the idea.
I personally support. That way if some less than Elite guy is taking crazy numbers of hits in iron armor we know that he is hacking and some Titan isn't hiding in a corner copy-pasting /heal <lessThanEliteGuy>. But they had better update the shop if they do remove it or else that will cause problems.
