After that, I'd give away what wealth I had to those who needed it. If I had friends who were always in need of gold it would go to them. Otherwise I'd just hand it to some low level character who didn't have heirlooms, since they'd be the ones that most likely don't have a high-level character to bankroll them.
My final act would be to move all my main characters to somewhere meaningful to them. I would take my priest to Ashenvale. I have really strong memories of leveling her there and that's where I think she'd want to be, defending it from the orcs. I would log out my shaman at the Throne of the Elements in Nagrand. Being a Draenei and a shaman I think he would want to be there. My very last act would be to log out my druid. I would take him to the Night Elf starting area and log him out next to that initial quest giver, standing by him, greeting each new Night Elf and help new druids as they come.
