During my RAF, I was boosting my Shammies in BRD. When I ran out of bullets and was low on food/water I logged out one of the shamen. A bank toon on that same account would load up with bullets and food/water in Shattrath. I'd hop out of the instance on the shaman who was on an attached account. Summoning the level 2 bank toon to bowels of Blackrock Mountain, just outside the instance saved me time and effort. How many level 2 characters can say they've been there?
