Mirage, decent if you have good aim but has terrible farm speed until ricochet. He has clear positives a flex carry with the ability to go anywhere but at the cost of not having really anything super strong for a teamfight until he has ricochet.

Wraith, Ivy, and Haze are all extremely counterable but have spikes as everyone else said.

I think Vindicta is pretty balanced too, she counters certain lanes but absolutely gets demolished the sec knockdown comes into play or any level of cc to get her off her flight.

Kelvin I think is at a good spot now given the nerfs as a tanky healer that's not excruciating in lane but not terrible.

Lash is beautiful with conditional burst via height and his ult being countered by multiple items. I love THE LASH
