Everyone who says rift is like wow therefore boring shouldn't had expected anything else.
It's like saying Legend of Dragoons is like final fantasy 7, or how Borderlands is like black ops, or how Virtua Fighter is like Tekken. Both rift and WoW are MMORPGS therefore they will share the same qualities, and especially since WoW is the best selling MMO, obviously more mmos are going to be modeled after it. Wow set the standards for the MMO genre and any other game out there trying to change it, is just going to fail.
Rift is still a new game, so of course things feel limited or more can be added, because honestly it could. And that's what later expansions are for.
