Exactly like the title says, Arena is messed up. Wrath of the Lich king arena is nothing compared to Burning Crusade. In BC yeah gear didnt require rating and it was easyer to get, but you got paired with teams who were equally geared. In WOTLK you can be startting a new team , lets say 2v2, but your 3v3 is 2000 rated(like mine was) and i kept fighting this 1900 mmr teams on my 2v2 when i was trying to help my friend who was not geared enough to face those teams. Dont get me wrong , Im not carrying him, i wasnt decked out either. Anyway what im saying is, MMR(match making rating) can sometimes be unfair. Maybe my MMR is 21000 but that is in 3v3 because my class/combo works well in 3v3, but when i face another high MMR 2v2 it doesnt work the same because some classes benefit more from each other in different brackets.
Also one more thing, i quit serious arena this season because of all the drama, now I am more into raiding. But last season when i was 2000 3v3 i hated winning 10 games in a row, and only going up by 40rating, but loosing 3 games and loosing 50?
Anyway, insult me if you want but this is just my opinion
