A was saying this for ages ever since OKW came out that the game is about flanking, capping but Schwerer HQ and Med Truck completly deny this.
Guess what was the answer.
L2P
personally i don't think it's too big of an issue with the okw because of the risks for locking down sectors, losing a tech building will most likely sink you. I would however change it so that the KT only comes out with all three buildings present.
also one thing about the OKW is that they can't lock cut offs with caches, that is usually what my flaktruck is for (not very exciting)
