I’ve been really busy gearing up my Priest the last few weeks and, friends, let me stress that if you aren’t running Regular Trial of the Champion several times a day you are missing out. This instance is far and away the simplest and fastest way to level your alts with more than respectable gear.
When I made the switch from my Hunter to my Priest I was rolling deep with Hateful PvP gear. I managed to heal a few Heroics with that Hateful gear but things were sketchy at best. Luckily, the awesome guild I joined was more than willing to run Regular ToC on a loop for me over the course of several days.
