People want to build there companys, the way they want how they want. If that means 12+ squads of mandos per company, becuase the player wants a company of commandos, so fucking be it.
Agreed.
But when doctrine buffs make the investment of all-commandos a lot better than the same investment in tommies, lts and captains there has to be a cost with them or doctrines completely force your hand in unit picks. If you do not have prices on them, theres no way to compare the buffs of t4 a vs T4 b when they both buff a lot of infantry, for instance. It also encourages spam beyond it being a possibility, it forces it if you want an advantage.
