my 2 cents:
on tutorials
I think the tutorials should be improved, because currently they teach you how some controls work, but not how to survive/win and they don't explain what formations to use in which situations or how you should use the terrain (just a few examples of what they should include).
on commanding AI:
I think being able to use the arrow keys in addition to the number keys to use the command menu, for example: up/down opens the "backspace" menu, after that you can use up/down to switch your choice, right to expand a menu and left to go back a menu and then something like enter/right again to confirm your choice. when you assign squadmates to a team (like red, white or blue) you should be able to command those squadmates with one button (as if they are a single unit).
