[open] repeatedly matching the same players in 1v1

It would be really nice if you added a few extra lines of code to your pvp matching to prevent repeatedly matching the same two players in 1v1s. The primary matching criteria shouldn't be simply that they queued at close to the same time. :(

Trying to do leo daily (win a 1v1):
queue for pvp, get matched against someone who can't kill me, and who I can't kill.
flail fruitlessly at each other for 7 rounds.
queue again, same person
flail fruitlessly at each other for 7 rounds.
don't queue again. spam /whois on the player name until they're in a match, wait 30 seconds, then queue.

I don't mind waiting a little longer for you to match me with someone different. Honest. The manual steps to do it myself should not be necessary. If your matching code is difficult to alter, a mutual concede button may be an ok alternative.

PS. On the plus side, preventing repeat rematching would address the current leo rep farming tactic of queuing with a buddy and trading wins.
