Dont have caches (there is 223 tho which DOUBLES income from fuel point) but can salvage wrecks. In 1v1 you will rarely see anyone build caches and in team games you have ost player to do it.
223 is Doctrinal. If it were default, that would be great but it would be considered OP as it is more of a viable choice, cost effective to build for a cache that can combat. I mean it does sacrifice CP, that is really the only downside I see so far. SO NO, that will not solve the problem.
The idea of Jagdpanzer is good. I believe it will balance it overall since OKW lacks in terms of proper AT late game where they are Heavily reliant on PanzerHQ. Jagdpanzer as a back up plan seems fair to me. Only Accessible after when PanzerHQ is built, even after when it is destroyed!!!
This should be a thing. Which other factions base is ever placed at risk. Most certainly an axis would never go to their base to destroy it. So therefore this is a fair and square implementation.
