At first, i had the enjoement to push my 3 shamans from 10 - 45

10-15 ragefire
15-20 deadmines
20-45 sm

A friend has lend my his mage -> deep frost and his warri -> dw
i have to say forgett the warri and take the mage
sm cathe was finish in 3 pulls but i think without the frost ele's nova i would be death quite often
Have tried strat with mage / warri but im not skilled enougt to do that right :P so questing was the faster way

from 45-62 (now) i have done quests but a friend who has boosted his pala with the same tactic
is already 70, got the figure of colossus trinket and has skilled prot to do aoe farming
and its so fast u wount belive
You can pull the whole cathe won't die and kill all at the same time.
In strat he is able to pull 4-5 packs of this nonelite/elite and it is dead easy to kill them.
I belive it is possible to take a mage and aoe them down but the pala is the save way.

Take a mage and do it till level 20 then, if it is possible get a pala

sorry for my english -> austria !
