I'm bumping this again because I think it's a no brainer that has been overlooked for a long time.
SP rocket artillery level II is equal to SP artillery level IV.
Rocket artillery level III is equal to Artillery level V.
We are talking speed, hit points and power.
When I upgrade the artillery to blue print levels the rocket artillery become a handicap to the speed of the group, are the first to be lost because of the lower hit points and just bug me being the only army in the group without a star over them.
We really need blueprint rocket artillery for game balance.
