I've always been hoping for the change to the cost of caches. The increase in MP cost to 250 makes most factions a lot more vulnerable to early rushes and harassment, particularly from the OKW and the Kubelwagen raiders. Plus, the OKW has early game AT to demolish the caches easily. This really had a negative impact on the balance of the game.
My suggestion is one that goes between pre and post patch: for each player the first munitions or fuel cache costs 200 manpower; once any cache is laid the cost goes up to 250 manpower for the rest of the game. This add a little more depth of strategy for most factions as you should pick a sector to secure early on for a lower cost. The durability, armor, resource bonus, and build time remain the same.
Overall, this change improves counterplay from enemy early game rushing and harassment if built early game. But the first cache doesn't have to be built in the early game. It could be build late game to make it harder for the enemy to cut supply lines and significantly curtail income. I want good opinions about this change, and if you dislike my suggestion, I want good reasons for it, not excuses.
