Cecilion has stupid range. Yu zhong is basically immortal if you play him right and his ult is infuriating cuz he just bops everyone around. Pharsa has a noob ult that just bombards everyone, like Eudora but several times over. Granger hurts like hell as well and is slippery. Most of the assassins because they're basically all built on stupid mechanics that make them unhittable. I don't play assassin doe.

I'd say Hanzo as assassin but he got nerfed recently, but if you can play he's good (although insta ban). Odette is pretty good cuz her attacks bounce around enemies and her ult is just a massive death circle, like gord but weaker but a full 360. Team her with Johnson and u have free kills. Not a lot of good Johnson's doe.

Esme refuses to die. Masha as well and Masha will take a massive shit on your turrets and lord. Masha is fast af, has high hp and high dmg.

Estes can get annoying when he heals and slows.

Chang'e's ulti is gord on steroids. Crazy DPS and high movement speed.

Silvana has a great combo as well where you're trapped in a circle and she releases all skills, but it can be avoided-ish by running around her in the small circle instead of instinctively running back.

Badang is annoying, he locks you into a u-formed rock formation and just WAILS on you, like a million attacks, and the hit box for the attacks is massive as well so if you're trying to get close to kill him to save a friend you're probably gonna loose a decent chunk of hp urself. And it can't be interupted as far as I know.

Uranus also has stupid hp regen and decent damage while copying sabers skill with the spinning blades and ridiculous slow effects. If him and Cecilion stand at either side ur kinda fucked.

Can't think of anyone else that's given me an aneurysm lately doe
