I am still against this. this game is about strategy. you desighn a map that provide a challenge. Bluffs, traps, and misdirection are all part of the strategy. World Wars auto reset traps. being able to watch your friends battles in world war reveal where the traps are, what is entended to be a bluffs, what troops you have in your town center and that tower.
no, I am not worried about what researches I have done in both the university and librarie. While that does change things in WW. I do not see how keeping that info a secret or revealing it will hurt or help you.
there are as many map setups; both good and bad as their are players. so revealing that info while you have a chance at winning does change thing greatly in the opponent favor. However after a war is over, then I think it does not matter any more. and if they wanted do an after war replay where you could watch your friends attack it would not bother me in the slightest.
