Well, I have a shaman lvl55+, and ill go to outlands as soon i get 58, but i can see that enhancement is not so good anymore for lvling... the mobs dodge and parry a LOT. So, ill prolly have to respect to elemental, and would like to see some builds at lvl 58-70
As ele have more mana, i think it will be better for instances, cse ill surelly heal, so i think a balanced build, ele/resto will be better, dunno for sure...
And if u think im crazy and should keep on enhance, please give me some advices, its my first char on wow, i simply love enhance, but first i would like to reach 70... thanks for ur help =)
