You're grasping at straws for these wow comparisons. Heavensward has nothing in similarity to Cataclysm. Sure there are some issues, but really the bulk of people saying there isn't anything to do were the ones that powerleveled every single job to 60 and all crafting and gathering too. Of course you're running out of things to do.

Cata was a failure because of it's stupid difficulty changes. Making healers have to "think about mana" all the while making their heals absolutely sucktastic meant you had tons of stressed out healers. It basically caused a mass exodus of all the tanks and healers who all rerolled dps. The raids sucked, and outside them there was virtually nothing to do. This trend continuing to Mop, and WoD, and most like Legion. Sure Final Fantasy has raids, but it's not the ONLY thing to do. Besides expansion just came out like a few months ago. Wait till 3.1 to see what you like about things.
