[Iron Giant]

I would think that a solution to the "dancing in and out" bug is a good idea. I like the solution of having the larger weapons with a longer range, or even have a weapon or two that will auto fire (if not used) during the enemy ships turn so you can't dance in, then out, of range.

However, I don't think that bases should be able to move. Spread them around a planet = yes, but move = no.

A moving Starbase is called a ship. If we want a ship, we can build one.

I think its realistic that a ship would attack a planet from the otherside away from the starbase right? So it doesnt surprise me that a starbase can't protect the planet totally and completely. For this you need fighters in addition to a starbase or multiple starbases.
