Since the FA now includes stock, I recommend caping it based on the corresponding potential of the other clan, otherwise you're going to see war clans make a bunch of different combinations of 6 player teams (each one only uses 4 players), and late game netting clans will find no protection from clan GDI. Without having to put skin in the game it's a "heads I win tails you lose" situation.

Honestly including stock is a breaking change and shouldn't be implemented, probably best to remove bushels and cash. It also gives a strange preference to stocking oil, so really the FA part is probably unworkable in general.
