Are people really complaining about the loot, is gated because it needs to extend the content or people will no life it and be done in a week.

If loot is your motivation instead of the actual raid experience than that's a you problem.

You can honestly unsub now because you don't need loot to clear content. 6.4 will be released and you won't need the loot to clear it. BiS Is needed for Ultimate and there are no more ultimates this expansion, so you already beat the game if chasing loot from raids/tomes. Crafted all you need for 6.4 and current raid gear is trashed for it.
