I get why you don't want to show player ELO, I even agree with it.

How about we show the relative ELO of every player compared to you? I think mystery about how your games are matchmade is what fuels a lot of these QQ posts. This would solve that issue, without actually showing ELO.

How about just simply show the ELO, and all the QQing stops....

There will no longer be any threads of "HEY PENDRAGON, WHAT'S MAI ELO KTHXBAI"

The mystery is the annoying part. When I logged on HoN, I was instantly attracted by seeing everyone's "leaves" and their Rating. This should be implemented in LoL, and everyone will be happy.

It's a tad bit of extra coding.
