Another alternative to pulling mobs too far is to occasionally ping their attention. If they're greater than 300 yalms from the fort, they'll completely drop enmity, get a temporary speed boost, and make their way back. Forcing a tag drop, especially paired with non-aggro status, could result in some unintentionally getting MPKed if they're not aware of the respective ranges. At that point, the proposition is just being a dick in reverse because some are just mad about things now.
Anyway, Campaign also needs some more incentives for people level 76+. Could be new gear sets like a +1 Teal/Perle/Aurore at 85, items you could buy for magian trials like Twilight/Daybreak Souls, and so on. I still think we should be able to learn the various campaign WS, but not all types are covered and some would require some nerfing in player-hands (AoE Doom, for example...). I would love having Uriel Blade on my RDM in Abyssea, as it would make an exceptional AoE farming WS that could be further boosted by atma you might typically expect on them.
