Tactical combat is too slow. If anything will keep me from enjoying this game long-term, this is it.
1. Let us place units.
2. Let us let the AI move units for us, but let us break in. (The AI is pretty smart, right?)
3. Let us turn off combat animations or speed them up. (I prefer speedup. It's less teleportish.)
4. Let us scroll the tactical combat map by the screen edges.
5. Let us turn off the auto-center effect of unit selection.
