Those two insta spawn mobs in AQ20 are pretty insane. I went from 54 to 62 in about 3 hours with non RAF with my new paladin group. Now I'm in the classic deepholm spots. You get flying at 60 and the lowbies can fly around deepholm. Gonna pretty much skip Burning Crusade, Wrath and Cat by grinding there. I used the summoning stone to get my slaves there.
