Ban as Many Maps as You Want to Stop Alt-F4

so was playing with my brother and plopy just now and thought about the following idea. (not my idea dont deserve credit). Ban as Many Maps as You Want to Stop Alt-F4. I think its a good idea. that way you can ban no maps to get a game faster or ban all but one map but it takes much longer.

I know cry cry but then the rating wont be correct but it would because some people would Just alt-F4 and only play one map... I am just sayin I think it could be a positive change for the community what do you guys think?
