As someone that doesn't play jax. I'm just going to give general advice, unless you have some sort of particular attachment with a character, like they are you favorite character or something, then tinker around with the whole cast and v find characters or a character that caters to your playstyle, although to be fair jax is one of the most versatile characters in the game so he of course is definitely a good choice with 3 variations that are all really good and viable. The fact that there are constant debates on which is best is a testiment to how good the variations are. And as a side note, why drop kung jin? Dropping someone who is "mainstream" isn't a reason to stop using a character, especially if you enjoy using that character, kung jin is a solid character, basically the definition of solid. Not to mention there aren't an abundance of them like there were at launch. Now I rarely see anyone play kung jin. His time in the spot light has passed just like every character, like how for a while boneshaper was, and before that predator, and before that raiden. I guess now it is deceptive reptile? But not really. Holy shit I'm rambling my bad I don't want to go back and erase all this so fuck it I'm posting it
