What frustrated me was some of the things i suggested were missing or a problem in the beta were simply ignored and were only after release was there an attempt to rectify certain issues in the game. I know i'm not alone here. I even tried asking questions on the forum and messaged Brad but to no avail, he simply ignored me much to perhaps their own detriment.. So much for Stardock listening to the community..
Yep, you were the only one suggesting things (or messasing Brad) and if there were other people doing it too, they were doing it in the same direction and with same interests and propositions as you.
1. Must have. No doubt about it.
2. Missed. I personally want Epic Events too a la Gal Civ II.
3. *shrug* Bottom of the list for me. Battle replays would rank higher though (when AI actually can stand on its feet with dignity).
4. I declare myself an ignorant so no comment.
5. Is this related to the "AIs designed to win VS AIs designed to roleplay"?
6. Russian roulette? In theory, the original idea was to have some random techs in the different trees so they may appear in some games but not in others (not basic techs though, only optionals). I liked that idea and would like it implemented. Plus we have frequency/rarity in techs. That's all the randomness I can personally accept.
7. That's something I have always desired.
8. Right now, I'd prefer to resolve the issues of Kindgoms conquering Empires' cities (or the other way around) and getting useless stuff, not mixing populations and all that. Rebel armies for the lack of food would remind me of old good days of Lords of the Realm. 
9. Not very likely to happen. Explained a few times that it would require many changes and more stuff. Latest person to try to explain it was Kryo, I think. He wasn't very positive about it.
10. Er... That's Civ V, right? Minors in Elemental are blood stains in the map.
