Something recently struck me, see if you guys understand this.
Worker units do 5 damage each, right? Right, they bring in a set amount of minerals. They attack the minerals and obviously do 5 damage which is what makes the minerals go down. Think of the amount of minerals a pile has as its life. When the scv attacks it it removes a portion of its "life" goes down. This got me thinking, what if you upped thier damage, shouldnt this cause them to mine more minerals?? Just a thought.
