I think there could be value to add instances to some specific areas.
I'm sure there could be more examples but I'll name a 2 that quickly come to
mind.
1. Zoo
2. Astacia
Want to run zoo? Too bad newb! It's already been ran today!
Get group together to run gaiter, notice loot on the floor on way...great, call
it off.
Instancing similar to how UHB mines was done could be a nice addition in these
examples. As it stands it's first come first serve which can be very
disheartening.
