Thank you for putting up all these points to the tech tree, The tech tree needs a greater revamp IMO. and am going to look at it at some point 
A lot of great points, but I have a question: what do standing army gives besides shields?
.
I suggest you focus your topic though, then put up 2 or 3 posts to different topics "UI Suggestions" "Tech Suggestions" "Bacon" whatever you want.
Sincerely
