I support this idea. Simplest fix is to increase rewards based on total numbers of participated ninjas in the war, that way only a very small number wont get rewards, while others with maximum contributions etc etc are guaranteed something, but in the end the leaders decide who gets what and still need to track given packages (don't change that, it's actually a good thing and offers organizations and weight for actually being a group leader, cuz you have to manage spreadsheets/docs for prize distribution and donation comparrison)
