I so about those Heros set we can save .in the descripton it say that these are made so we can quickly change are Heros set if we are like set to grind ressource but then we see someone comming to attack are city quick change set , but just how fast can that be if we have to re do are skills this is anoying to me.When we set and save a set up of are Heros equipment and skills should be save for that one, and so on ,so that when we need a quick change of Hero equipment and skill should be all set, no mater if it is for a campain or grinding,this is to me the meaning of quick change.
