Feedback to brits:
1. Infantry Section
I feel like double both (target size and moving accuracy) maybe too much. Not early game when they have 4 men but later, at stage of 5 men - not to meansion when they will be equipt with 2x bren. I think we should let one of those buffs go OR make medic/pyro upgrade requiring 1 weapon slot. If not i fear we will see old Tommies blob back. Smoke idea is great. I would also look at the unit price. I think there is a bug there.
Is there anyway to buff them when they are 4 men and not when they are 5 men?
Making the pyro/medic take a weapon slot is an option.
Alternative is making the 5th upgrade optional per squad (for free, after the tech is unlocked) and making it require a weapon slot.
The problem with IS has always been the late end game scaling.
