Best hard carry tops?

{quoted}

Who are the best hard carry top laners beside Darius, Riven and Fiora?

The term "hard carry", typically more often used in Dota 2, refers to a champion with a particularly strong late game.

Only Fiora and arguably Riven of those you listed would fit that criteria. Darius' scaling is situationally good, but often he is too easily kited to be effective late.

These are some top laners who are also quite strong in the late game.

I get the sense that what you meant by "hard carry" was champions that can snowball and hard carry off a lead.

I don't need to list anyone else. Just play Quinn.

Darius, Riven, Fiora, Renekton, Swain, Quinn
