I agree on the part where you state that structures should get more HP when the team evolves, I also think the radiation poisoning thing from Godmil is actually a great idea. Finally, the damage the blaster does is really too low in my opinion, it takes ages to even kill a soldier with that thing. Upping the dmg a bit might even move people to use the blaster! Nothing wrong with the rate of fire or the speed of blasts though, it's a real skill weapon ;-)
