Based on how the start of S3 went, its really the luck of the draw. I met as many suck ass teams on my hunter as full S3 teams. We got to 1600 the first week and my hunters max rating was 1800. I was average 1700. So its just random who you get matched up with. Also there is a "gear" check I thought ? So you should be able to keep 1500+ if you were 1600+ before.

I only did two weeks of 10 games with my noob shaman. I have no healer.. i was losing every game until i repsec my paly holy and made 4 hotkeys that have him heal a dif shamy, and when he hits that hotkey the shaman have the casting macro there as well( using G15 keys for this ).. so no matter which shaman hes healing they are all DPSing. Its a short term fix, until I find a healer who will grind it out with me and learn with me. Anyways i was 0-8 before i did that and won the last two with the new heal macros hehe. I would have played more..but i was grinding EotS tokens and it was late 8P
