the garrisons thing has been like that for quite some time.
7 countries on LU, 7 countries on WG, 7 countries on FB... amounts to allot of lost money via weapon/ammo quality dropping when stuff is put into the gars.
Serpent, a while back sent a message to GM regarding supply bugs. and they know this is how it works. so its just the way it is. so now, we *have* to spend tons of money on upgrades to keep us safe from nukes.
W3C mentioned some where that fighting quality was much higher than the war engine could handle. and then they turned around and increased the fighting levels... honestly, upgrading is a money pit. that is bigger, the bigger your military is. none of the worlds really produce enough upgrades, and the upgrades degrade at an uncomfortable rate.
seriously, i doubt much will change, because this is costing the guys (and gals,) with large militaries, MUCH, more than the average player. so most likely, until certain cash reserves have been crippled, nothing will change.
personally, i don't really see this as a bad thing. some of the underlying complaints about the war game, is the obsessive size of militaries, making the war game tedious. and the gross mismatch of size of older players, to mediocre players. such things as ammo upgrades, unit fighting levels, and limited military set of supplies (bombers for instance,) are the best things going to reduce the over all size of militarilies.
only problem with it, is people like me that know how to get around certain limitations. and can maintain their old level of military... and of course, those of us that can, have to, to protect ourselves, from each other.
