Why are you worried?:
Because I'm afraid I'll enjoy it.
Why are you afraid that you'll enjoy it?:
Because I'm concerned what happens 2 years from now.

This marks the 4th consecutive expansion with a complete gameplay overhaul. WoD looks like tons of fun and I know I'll enjoy it, but what does the future look like? Is WoW going to experience another complete gameplay overhaul 2 years from now?
Some people react well to change but many of my friends who have quit have been directly because of change. The gameplay they enjoyed is now gone and they aren't interested in the newer versions of it.

I'm just preemptively being concerned about the future development of WoW and whether or not the gameplay presented in WoD will be left in the shadows despite success, or if it will be left intact while properly built upon.
I think this is a valid concern, so what is your opinion?
