back when WLs where introduced, i fought very hard to make sure the reward for going up in war levels was worth it. originally, the GM wanted a one time GC award, but a one time award, for a permanent increase in difficulty, was a sour incentive.
getting them to increase the cash per C3, was nice. but now, with the GC market gone, the new monthly award system, and a huge advantage given to higher GLs, and WLs. with advantages given for being out of protection, at higher WLs. i'm not sure huge cash amounts in C3s, is necessary.
i think that Aries is going in the right direction.
