I just activated my 4 other accounts last week. My main is a prot pally. I think about 930s.
I did the first zone with quests to 101 and was not liking it.
I have stuck with instances ever since. They are at 108 right now. They have heirlooms that give me like 50-55% extra.
Though, I am powering through the instances. I am using it to tweak my setup. I try and make a few tweaks each day and get a little more optimized.
I get about 120k xp from the dungeon completion.
