Bring back the XI outpost warp system. NPC/crystal that allows you to teleport to a camp, at the cost of gil. Whichever GC is holding that camp gets the warp for free/cheaper. Can only teleport to & from crystals ( like aetherite gate passes ).

As for the comment above, HNM camping was mindlessly boring. "Spending time with friends" sitting in a room filled with other people scratching their privates waiting for a pop, pfft that's not playing a game. You can do that in Ul'dah.. I would agree if you were going to say something like sky/sea NM's or something. That was a lot more fun. Although I guess your point was the journey rather then the destination, which yes I agree - travelling is a big part of it.
