I've been thinking about this for some time, and I think it could be implemented. It's supposed to be more realistic in how units work. In real life, armies and fleets attack other armies and fleets, and take losses, loosing a few ships, tanks, artillery pieces, infantry, etc. In degenerative diplomacy, units will, well degenerate! It works out as sort of a Hit Point system. Each unit starts out with a certain number of hit points, I'm thinking in the 7-10 range. The units loose a HP for every time they attack or are attacked, so if a unit attacks another unit, it and the other unit loose one HP. Support moves are simply the same thing, if one unit attacks another and is supported, the unit being attacked will take 2 HP damage, and the unit attacking will take one, but the one supporting will take none. Support holds are similarly the same thing, If a unit is being support held and is attacked by a unit supported by another, all units will take 1 HP damage. If just one unit attacks though, only the territory it attacked will take damage and the support holding unit none. Once a unit runs out of HP, it will automatically disband, allowing another unit to be built to replace it. This degeneration is in place to make the game more realistic as in how armies aren't invincible and perfectly even all the time. Let me know if anything could be tweaked or changed and other things elaborated on.
