His claw nerf made him much less cancerous but his dash needs to be tweaked. It has iframes, cleanses everything including Tyra's mark, restores ammo and heals and you can spam in near infinitely. It's too rewarding for how frequent it is. Either remove the cleanse, increase the charge time or add a internal cooldown on the buffs so even if you spam it you can't always get cleansed and heal up and such. They did the same to Nessa's teleporter and Strix's invisibility heals so there's no reason this can't be done.
His dashes while op, make up for the lack of damage in his base kit as they allow him to dodge enemy attacks frequently. I've heard people suggest that they lower his fire-rate but buff his base damage to not only make him more skill-require but also more of a threat in a 1v1.
