Ok, so I am one of the idiots who drops a lot of money into this game and this suggestion will actually be bad for me, but good for the gameply overall I think.
Well, gate alerts are just stupid. They do not give free and paying players a level playing field. With gate alerts, attacking someone without a speed up in most cases, is suicide. Why not make the game more realistic and remove the whole gate alerts thing altogether ?
Maybe give the gate a different purpose, ie. improving the health of your units or your defensives or whatever else.
