If this was the first time they limited features due to performance issues I would agree with you. But do I really have to list out the things that are limited or out-right removed/cancelled because the game couldn't handle it?
Listen, I really enjoy this game overall. I've got a ton of alts and have been subbed non-stop since launch. I'm not going anywhere any time soon. But if I'm going to pay every month for a game, I expect it to keep growing and evolving. And when the game hits a wall while developing a feature I expect them to figure out a way to move that wall or work around it. Not just throw their hands up and say "Oh Well. Maybe some other time."
