It's suppose to be like a bunch of toys are fighting, that's the mood they were going for. The units look cute and have a nice fantasy steampunk vibe that vehicles are much easier to pull off with. As I said before, vehicles are easier to use in a game than infantry- if you have looked at any of the gameplay you will not how rapid combat is yet how simplistic the graphics are. I just do not see infantry fitting any niche in the fast paced, rock paper scissors combat that the game has managed to produce.
