Publicize hidden rankings

[awpertunity]

No they should not.

There's a reason games like starcraft/dota don't do this. It's generally very nerve-wracking to play games knowing you will immediately see the effect it has on your rating, and this leads to people playing less games.

People wanted dota to publish MMRs for so long that they finally gave in, kind of. There are now two modes you can play: ranked or unranked. In ranked games you immediately see the effect of your game on your MMR. You also still have a separate MMR for unranked games, but you cannot see this (so this is not the same as friendly games in Outwitters since that's just completely random matchmaking).

I couldn't find any actual data on this, so this is based off my own experience, but it seems to me that there are a lot more unranked games of dota being played than ranked. It generally takes me 5-9 minutes in the queue to find a ranked game, and under 3 for an unranked game.
