Might be worth speccing enchance for a week or so just to do the 8 x ghost wolfs. Pop that and sham rage and hope you can kill 1 or 2 guys before they kill you. Least then all you have to do is mop up.

Im not really looking forward to arena, Last time i only got into arena at the end of S4 as id only just hit 70. So that was a fun lesson in 10 losses a week for about 6 weeks.
Im sure it will get better as gear disparity is reduced anyway.
