Not sure, I think I posted these questions in the wrong thread (there's one in the Civ:BE Discussion forum, and this thread in the News Updates forum) so I am re-posting here:
1. Why not keep the option (from Civ V) to select different upgrades for each unit, rather than the same option for every unit in the class? I liked the idea of specializing some infantry as healers, and some as attackers, for example.
2. Why did you remove the 'luxury' resource concept? It seems like you could still use some of the resource types to boost health (similar to luxuries and happiness), it would make the new alien resources seem more valuable. As it is, they have little impact other than making me build a paddock/plantation instead of a farm, whereas in previous civs I would plan city placement around those resources.
3. Will we get the ability to rename specific units?
