The bases are fine the way they are. I am against spending too much time on doing the bases.
1. Fancy decorative bases take valuable time away from painting.
2. A plain painted base can be repainted to better match the terrain. The battle will be in a jungle, paint it green, next week on Mars, paint it red, in an urban area a nice gray will do. Nothing like a beautifully decorated base that doesn't match the terrain of the battle.
3. It gives you a place to mark which figure is in which unit. Unit A from the Red Army is in hand to hand with Unit 1 from the Blue army. Then Unit C from the Red army joins the battle, as does Unit 5 from the Blue army. Casualties are taken by both sides. With a plain marked base it is easy to figure out loses for each unit. After running a couple GASLIGHT games were several units mixed it up, I came to appreciate the usefullness of having clearly distinguishable troops.
