What be the point of playing those who you play with on a daily basis and use tactics you know will work on them?
Let's make this a fresh challenge every time.
TMM should have option to (or will outright ) hide your opponent's name (replace it with some random name) and hide rank, so that for each and every game you play on TMM, now you have to truly adapt based how opponent plays. Then at end of win/loss the opponent's name and rank is shown (or is shown in replay).
Keeps things fresh. And prevents players from disconnecting right away if they recognize a player they dont want to play with.
