I actually made a post about this I believe awhile back ago, it never really got much support because teaming wasn't nearly as big an issue as it is now.
I personally love the idea tho. I am one of those people who likes to play alone or in FFA's with friends. I team sometimes just as everyone does though.
One thing I see from your post chad is that you say that servers 100 and above would be FFA's, I feel these servers need their own spots in the hub like Classic and QQ has. That a way, people can't accidently join a high server and team, claiming they didn't know it was a FFA server. It will need to be 100% clear that the servers are FFA ONLY.
Also, with the fact that people are obviously gonna try to team on these servers anyways because there are always those certain people who just have to break every rule they possibly can, the thing if everyone looking like steve and no nametags above your names would be a MUST, else these servers will just be infested with teams.
But yeah, it would be a relief if I could play some games without killing countless teams of 2-5 players lol.
Well if the team just stays away from eachother the whole game, then its not really teaming
. As long as you aren't getting 2v1'ed, then there is no issue right? :O
