Mainly the quests were dull despite how gorgeous the zone was, and ontop of that combat was hell for melee, dealing with a z axis and all. As ranged I didn't mind it one bit.
My problem is that I faction changed and lost my portals to it a while back. Thus I don't have a way to get back to Vashj'ir unless I've been missing something.
You can just fly there with 310% speed. A fatigue bar will pop but you'll make it.
