Leveling from 85-90 sucks if your other characters are 120. This macro let's the lower-level character sit in the House of Thule zone next to the Mercenary Quest giver, Rupocc.
PL'ee (lower-level character) is in group, sits next to Rupocc, and initiates this macro
All other characters scatter around the zone and kill the appropriate quest mobs. I had 5 characters in various spots, using a custom "hunter" macro, looping waypoints.
- Rotdogs and Snakes:Courtyard
- Skeletons and Bone Golems:NE section of zone
- Terror Guards:House lobby and other areas
- Bone Crafters and Quaking Haunts:NE Section and other areas
As each quest is satisfied, the character being leveled completes and re-requests the quest.
Without a lot of effort, this got 85-90 in less than a day. Which for me was good enough.
