I'd like to preface this by saying that I'm not fully affected by the meta changes regarding ADCs, it's a role I don't play a lot of.
I actually like the recent meta changes. Being able to play various roles in botlane and trying out different combos is a hell of a good time. It gives me and my premade room to experiment. I'm not for reversing Riot's decision to give botlane a bit more color and fun, however, I do think that Riot should at least do something to make marksmen viable again.
Because what's the point of having marksmen there when they can't even do a damn thing.
