90% of my games is on MP ......
And yes I do set rally points all the time. True rarely on different planet since I tend to build factories on worlds that are border world or 1 phase jump away from where i will be fighting. If i go into fight and constantly bring reinforcements if I would set up rally point on a planet it would mess up what i want ships to do when they come into the gravity well (not necessary travelling in gravity well when i need them in fight.
So I rally either on edge where they are supposed to jump in but most of the time my rally is on capital ship....
