No. You get more satisfaction out of the game because it's hard. In a similar fashion, you identify more with your character because of your talents. I have, for three years, played Balance. I got Hurricane as a talent (granted, about a month before it became trainable and Moonkin form replaced it in the tree). I love playing Adoriele because she's Balance. If/when talent points become useless due to the relative ease of switching between them, the ability to identify with your character gets lost. What makes Adoriele different from any other druid if all they have to do is head to the trainer and respec with no associated cost?

If they remove the reason to keep your talents relatively static, they remove any need for them at all.
