Need help designing my own RTS!

Hi Guys, I'm creating my own RTS with a team of really awesome developers but I wanted to reach out to the community of RTS players to help me incorporate and design amazing, fun to play features. The RTS will be set in prehistoric times. I myself used to play command and conquer red alert 2 avidly and Im just geting into Age of Empires 2! If anyone would be keen on joining a focus group for my game itd be great.
