Zac - May not do as much damage, but you wreck teamfights by displacing enemies and doing aoe damage
J4 - Also great at all stages of the game. He does damage if you go warrior then tank, if not, he is still good at locking up their enemy carries
Vi - Great ganking, shines in mid game, does a ton of damage, but in late game she just becomes a low/damage huge tank. Her only use it to ult their carries in late game, still good pick
Wukong - Same as Vi, good ganks at 6 and pretty good damage. He can stick to enemies and dominates teamfights late game
Elise - Requires more of a skill cap, but she does huge amounts of damage early-mid game and she becomes very tanky into late game. Insane chase ability
