I still box Rift, currently on Alsbeth. Gearing in rift has more options I feel than WoW did (which I boxed until Rift was released). You can get gear from PvP, dungeons and then the actual rifts.
The add on support is a lot less for Rift than WoW but overall i still enjoy it and being a casual player makes it a nice change from WoW.
Takes a lot more power to box on single machine though, most boxers I think run the main client on a low/medium setting and the other clients on the low setting which needs a restart of the game to enable.
