Wow. OK I gotta ask - how long have you been playing D&D? And I guess which editions have you played? It sounds to me like you're not experienced with a wide variety of play tables and playstyles, but perhaps that's a mistaken impression.
I have been playing for 30 years. I am mainly experienced with AD&D, Classic D&D, and 2nd Edition, but have considerable experience with 3rd Edition. I have very briefly experienced 4th and 5th Edition, but the latter I studied carefully as it was developed, and gave feedback regularly at wizards.com. I'd say I have seen a lot of the playstyles out there, having been to several conventions, where I actually found a niche as a host and tournament player.
