What do divers have no scaling into mid-late game?
I mean besides Irelia, who is really strong at all points in the game.
and a bunch of other divers just don't do well late game, not enough damage, while also getting blown-out instantly in teamfight.
Hecarim may have a potent ULT for teamfights, but it's the team that takes advantage of the CC, Heca himself doesn't really do the killing.
I consider her quite potent in the lategame, thanks to her Q2 converting all damage to true damage at that point.
