I'm 5 boxing as well, at 28 right now, and just trying to find the time to play a little more. Probably this weekend, since the weather may be a bit cloudy here.

Doing a cleric tank and 4 chloros and it's a load of fun. Instances are easy (lower level instances I expected to be simple) and looking forward to trying out some specs I have planned for experts. I have a main 50 chloro who's done most of GSB, so it was time to start boxing. Already had someone youtube me killing them (lvl 25s vs a 50).
