at least you can manually move your team forward though the boundary when you know one is coming up as long as they are all on the same quest. ( my arrow keys move my whole team forward )

it's 1000x worse if you are trying to level up an ALT to catch up with your regular team.
the ALT will invariably be on different quest and thus he will NEVER see your other characters, you are FORCED to solo box the alt to catch up.

SOLO IS SO BORING I CAN'T STAND IT.
