I don't see any problem with maintenance. It helps a lot in long games but in short ones it is totally useless. For example if you meet a race with high maintenance reduction it only means that you have to attack fast so the race doesn't have time to benefit from the low maintenance cost.

The balance problems aren't an issue to me. There has to be some bad tactics and some good ones. If the game were in perfect balance it would be much less interesting.
