Originally the point of the sightseeing in ARR was for you to use the hints from the description to find the spot, indicated only when you see "you've arrived at a vista!" It was meant to be a sort of sightseeing treasure hunt - rather than just "here's a point of exp if you do /lookout!" it was more about the exploration and discovery than just a free point of exp.

Tbf, a lot of stacks only recently increased, and plenty still go to 99. What can ya do?

Reduce-able stuff is easy - hit your collectable action, and anything reduce-able will remain lit up. Anything that darkens isn't able to be reduced.

No comment on flying mobs, but they're slowly adding to the list. Though since Battle Panther can fly, I'm kind of surprised that Coeurl can't. XD
