I already suggested that a couple of times, I KNOW IT. but i see DEV,s are getting closer and closer to this reality.
Stationary guns, should have a system equal to Tank/Aircraft, you select you Engineer squad, then you select a AT gun, a AAA and a HMG.
sounds OP? absolute no, because each theatre will have its own tree of Stationary guns, so you wont see the same Stationary guns in Moscow that in Berlin. it helps balance the game, give more guns for us players, and more things to eventually buy.
Premium Stationary guns should be nice two.
Cheers.
