I only did Duoboxing with HKN. I did not get a warning until now, but i stopped using HKN. I made a few new macros and am alt tabbing now.
My comp is 2h fury and hpriest. I mostly do jumpruns wich gives me around 300g/h.
But i can do most 5 man dungeons with this comp. Strat baron takes about 80 Minutes.
I also tried lbrs, strat living, Tribute, and brd. My Warrior has raidgear and my priest only has prebis + Benediction.
I still have a lot of fun.
