Basically if you removed "X" unit from the game, then "Y" civilization would move very little from it's current position on the tier list. Going to allow everyone to select three units to give us a bigger sample size. I have Diety AI in mind but feel free to vote/comment as you see fit. Hoplite: Suffers same problems as unit it replaces. Requires you to build multiple to get benefits. Ngao Mbeba: Defensive bonuses are weaker than offensive ones IMO. Beserker: +7 attack -7 defend means too many 1:1 trades. Crouching Tiger: Loss of that range really hurts. Domrey: So incredibly expensive for a civ that already has production issues. Really needs a +50% card. Samurai: Good unit but not being able to upgrade from warriors hurts timing push. Sea Dog: AI just doesn't build enough ships. Rough Rider: I already own most of my own continent at this point in game: Digger: Comes too late. Most coastal battles I will fight with freights at this point anyways. U-Boat: Comes too late. Replaces a unit that is already weak. How often do you have open ocean battles? P-51 Mustang: Comes too late. Replaces a unit that is already weak. AI doesn't build aircraft so not much use for fighters.
