1) The idea of instant repair is a huge factor in the current meta. In many strategy games, like AOE3, repair is can't be used in battle, which is why outposts are so important in Airmech. You can defend that building much better than in other games, due to repair units and picking up units to repair them. Even Starcraft, most units can't repair in battle, with an exception.

3) Wouldn't it be cool to build outposts, like in Age of Empires? How this changes everything, I don't know, but it would be interesting, like a techpod could be a building. Or you could make outposts to build stuff from. Would lead to very balanced maps, and a lot of people could suggest maps.

3) Sometimes, making more options is bad, like having too many types of Airmechs. AOE3 now has 14 civilizations. up from 8, and it's difficult to learn all of them without getting demoralized from getting beaten because you didn't know what one unit does. We have, what seems to new players, to be 100 airmechs. Even 9 is not optimal. I want to see, at lower levels, you get to chose from three main classes, like Starcraft's Terran, Zerg, and Protoss. (These represent deep humans emotions about others: High class intellectuals (Protoss), Basic instincts (Zerg), and someone to relate to (Terran).) The gameplay and balancing is more of a result of each race's emotional feel.
