I myself am taking a break on multiboxing till things eighther get eased up on heroics via nerf or new raid zone via content patch so that we can have more ways to use Jps. I farmed all the needed JP items for my team, and made my epic items on few characters. I managed to down few new heroic bosses such as the BRC first boss (second was just plain practice but usualy am just tired of trying. I know it can be done, it has been done by some of us).

I have done what I could, so now am just on solo account till things get more accesible to me. Maybe in a few months after first content patch gets released will reactivate other 4 to try new things that can be done.
