Agreed. I enjoy the fact that I can run around with the spec I like. There are some fights with gimmicks, where one spec really shines, but in general it doesn't matter as long as you play well.
Besides, look at this:
[H2P] Heroic Raiding: Talent Choices (25 man T14)
So the "Hardcore wannabes" still can just read it up and spec FOTM.
