It would have been good, if energy costs per terrain type was like first conquest. This morning with full energy I moved 14 tiles (13 grass, one forest) and have around 70 energy remaining. Moving on grass should take less energy. The 40 energy per grass tile is just too much.
I know we should build watchtowers to make roads, but at very first day, there will be not a lot of watchtower roads. It would also be nice if energy restored faster in forests (food by animals and trees) would be somewhat faster. Or at claimed land plus stronghold, that energy should restore faster. So staying on a watchtower under construction or something like that.
