Barring soloing Kara and ZA, it seems like 10-boxing just doubles your downtime on things like dailies and quests. Almost like you hit the top of the hill at 5-mans, then anything past that starts wasting time rather than just gaining it by not pugging or waiting on guildies.

Was just wondering. I spend almost all my time (literally) doing heroics at this point. I sure wish wowarmory.com would update, so I could analyze my newest gear setup.
