so i have been looking to do multiboxing for a while now and now that i have the hardware i order i was wondering what do you guys do at lvl cap i was thinking of doing pvp but blizzard threw a spanner in that (yes yes i know you can jerry-rig it to sorta work but if blizzard is working against us in BG/asheran then i don't wanna do it in the first place) so what do you guys do? in my optic most raids are solo-ble so no need for multiboxing to run them arenas are kinda ok i guess but seems a bit dull in the long run
