The artillery pieces only shooting four shells really sucks ass, as if they weren't already obsolete enough as it is, they should give them manpwer decreases if they only gonna shoot four shells, well the german one can stay the same price becuase its not very likely to get bombed but the soviet one is almost guarenteed to get off mapped most the time you dont even get to use it more then once it needs to halfed in price.
Well you haven't read that cooldown from barrage also reduced, so DPS remains the same.
