Specifics about your multiboxing
What software are you using?
I tried Karazhan before but only managed to down a couple bosses. But then recently tried again, with my 5 pali tank team at around 880 iLevel everything was fairly easy, no wipes.
Reached the point in the expansion where I am bored, same with every expansion. Now would be the time I mix things up. Either switch to 10 boxing, or just level a new team.
I don't see 10-boxing as helping much this expansion, maybe instead I'll just level up a couple more teams, start with my hunter team.
My subs expired today, going to hold off playing until tuesday to see what they do with the 7.1.5 patch.
