One of my fancy ideas was to take 5 characters to farm Volatile air's in ZG. It's a reasonable simple path, zone in, cut left, kill the mob, loot, leave. I can get it working kinda ok but I always have to switch off broadcast at some point to fix their pathing.

Anyone do the multiple instance thing with multiple characters and have suggestions on how to keep their positions in sync? I get that fighting throws it out the window but even without combat I still manage to get out of sync pretty easily.
