Uptown i think there is no way to improve the strat system without penalizing one country to much, country A hits country B's strats thus affecting the supplies and what they can access for country B, some players for country B don't like not having access to all there toys and change to country A or C to have access to them. you have to try and make all (or as many as you can) players have the same level of enjoyment without taking away to much from the others, its not an easy formula for HT to come up with.
