I started 5 shammies about a week ago. Been playing long hours, usuallly watch movies while i grind (i use a 70 mage to power them through instances over and over 4 at a time).

So far they are all lvl 46 with about 5 days played. I pickup alot of loot and I know that slows me down alot. Just yesterday grinding them through ZF I made 700+ gold from the drops.
