I couldn't take it anymore and just ditched my 4 new chars. 3 of my 4 accounts were previous accounts I already had when I was dual boxing. All 3 accounts have a character in their mid 30's! I managed to find a priest, druid, mage and lock all near the same level. Had to do 3 character transfers to get them on the same server.

Sadly the server is PVE and they are allies

But at least I just skipped ~16 levels. It is hard to play 4 different classes though. But when everyone is fully buffed, they have hella stamina (blood pact, fort, motw), lol.
