help settling arguement on map

[PalidinMaster3]

My friend and i are have a dispute of a map. We're making a wc3 map based off an internet game and we're trying to make it as real as possible. Defend Your Castle from www.xgenstudios.com. Now he wants to make an archey range that trains the archers instead of have a tower that is upgraded, by an interger value or decreased. I think my integer idea confuses him and he doesn't want to do it. His idea uses food cap to stop production. In real game you can get 800 arhcer or more and wizards and worksman. Remeber trying to make as real as possible. I'm using archers as an interger value of multiboard. Which is better

sounds good, but you really dont need a multiboard, just make an event that when variable = xxx, upgrade building.
