Why do people care if there is an adoption center? Just because you don't roleplay doesn't mean that it's not worth the time adding it for those who do. Roleplaying is something that is self-sustainable. You need to create it one time and it gives a good portion of the playerbase something to do without the need to create any more content for it. On the contrary, creating a dungeon is something that takes an immense amount of work, yet the content is only enjoyed for one time. Then it becomes a useless chunk of server.

So roleplaying areas take minimal effort to create, yet offers some portion of the playerbase something to do without ever losing its purpose. I don't like roleplaying either, but I think roleplaying content has a very nice effort:benefit ratio for those who do enjoy it.
