Win easy when 1v1 and you have a priest you can make friends with or have a friend priest queue with you.
Ok, please take it easy on judging me on my post this is my first post to these forums. Anyways on to the way to win.
Ok first off I used zemsta's technique (Highmaul Coliseum Acm + Title + Chest new method.) to make me be in the final 4. I joined the battle as a healer so I could somewhat survive until it was 1v1 the way this went down was It was 1v1v1 me a priest and a Feral druid. The feral druid killed the priest, the priest got pissed and then use Leap Of Faith on the feral druid to pull him out of the arena. He did not actually get pulled out of the arena but it did make him lose and count me as the winner. I am not 100% sure this still works because I have not had time to test since yesterday and Im not to sure if they patched anything but if it helps anyone I put the information out for you all to see have fun and good luck.
