Item slots

Hello everybody. I dont know if someone before posted something like this, but i was thinking about adding a special item slot for control wards. Because if it comes to late game and u are all full build, u will not have much vision because everyone will have trinkets, tracker knife is removed from game and 3 wards from support are not enough for good vision in jg, that can be rly important late game. 1 pick in jg can decide all game. I would like to hear Your opinions.
