My rating in 2's is currently 1630 and just came out of a match with a disc/ret where I ran out of mana and the carried Ret could just stun, wings, reckoning, divine toll, templar's verdict me since the priest was able to keep him alive. Even an undergeared ret can kill you in a stun with his huge burst. Turns out.. while I was playing at 1630 rating, that the disc priest was 2410 in 3s with full duelist gear. Even in 2s his rating was 1800. Why was I playing against him while I was still at 1630? Blizzard needs to fix their damn MMR system.
