Marksmen in other lanes
Certain people want marksmen top lane, or mid lane. But here is the problem. It doesn't work that way. If you nerf Marksmen out of Bot lane, they won't be strong enough to go anywhere else. Top: Though they can poke, they can't win 1v1s, if lets say a bruiser gets on top of them they are dead, being the only saving grace for melees top against ranged champs. Jungle: Their clear is garbage for almost all champions, their ganks suck, and they are squishy and can't 1v1, same problem as Top. Mid: Some Marksmen can do good her, but most can't, because Assasins one shot them, and Mages out 1v1 them. Same as Top, and Jungle.
So these theorized nerfs on Marksmen do not push them in another direction, they only take them out of the game. If marksmen leave bot, they have no home, no lane to go to regularly, as they are only good in niche situations. But then if you buff them to go Top, Mid, or Jungle, what is stopping them from going Bot, and taking back the botlane meta?
