Eureka Pagos seems like it was designed to isolate lower leveled folks and higher leveled folks, and discourage people from helping each other. Why? The map design, the level required for mounts, and the reqs for using aethyrite crystals.
I should state, that I am indeed level 35 in Pagos; however, my point still stands. There are some critical flaws that could be improved by several things.
1) Add at least one more way to get to the top area. It's too much of a hassle for people to get around and level where they would be best suited because of how long it takes to travel.
2) The upper aetheryte crystals attunement requirement should be lowered to 28. that way people can fight mobs that are at their ideal level. Though the aetherye level req for the magnetic studies is just fine.
3)Chocobos should be usable at a lower level. Especially since the people who would need to use a chocobo the most, are people who CAN'T use the aetherytes!
Doing these things would greatly make it easier for parties to get along. Rather than leaving folks to die alone because it just takes too long for people for traverse the map.
