I 4 boxed in Everquest so I have no problem with it for as long as I've been playing, I started a 2 box in eq probably 7 years ago. To me its always been a cool idea, not needing help for stuff and controlling all the loot. I've never boxed on a pvp server, and doubt i will since I'm not a huge fan of pvp servers in the first place. (I'm a poor sport, hate being messed with)
