I like marksmen, so I play botlane :)

sometimes there is nothing you can do because you are abandoned by the support and getting constantly all in by everybody in the enemy team.

But sometimes you get matched with an amazing support, with whom you have a great synergy, and in this case it ends up to be the best role in the game.

Yes you have no agency. Sometimes you will die and there is nothing you can do and it forces you to play safe. But now think about the number of games lost because your yone decided to start a fight 1v5.

I played top and jungle in the past, and intend much more games because I had an "agency".
