In the future, dragon pit should be located in the midlane.
If summoners rift ever gets another map update at some point, I would like this to happen. Currently part of the reason why botlane is so strong is because, winning bottom lane will usually acquire majority of dragons, due to objective literally being next to them. Most midlaners can't solo the dragon fast enough by themselfes, and it would also finnaly give top laners a chance to match bot lane in early game fights for objectives and influence the game more.
