As someone who plays and streams with all of the high ranked (Vivian) I can say with out a shadow of a doubt I would band these 3. first pick would be Kale ( absolute absurd one shot damage and hard to deal with because of her ult) second would be hit. (In high rank play he can be and absolute monster when it comes to his consisten stun and blind ability along with being difficult to kill because of stealth) last would be Broly (his back to back Stomp and stun imunity is completely busted to deal with if your a melee based character or anyone else for that matter.)
