My 5xShaman team was great fun and made me learn a lot all the way to 60.

Now I am having a blast (literally) with my 5xMage team. Arcane Explosion AOE farming is great. They are closing to 50, moving fast (to my standard, I already have about 3 days played I think, I am very inefficient in terms of pure levelling).

Next in line is 5xHunter, they are around level 30, and indeed great fun.

If I still have RAF time, I will probably go for 5xPriest, or 5xDruid.

All these teams will be mixted into new groups (together with my existing level 70 characters) when my RAF period ends.
