I didnt change much gear from 60->70 on my warlock who had the best gear from BWL and a few pices from naxx/aq 40.. I even remember the warlock from Last Resort called mindel or something dooing high king malugar in Tier 3 so it will be exiting to see..

But since everyone gets a fresh start i assume the same thing will happen in the arena and that they will reset the arena points due to that it will be EXTREMLEY unfair to DeathKnights if people are able to start with 5000 arena points.
