Jax's Counterstrike (E) Still doesn't work the way it's intended.
I'm a plat Jax main, and while I'm definitely not the best at Jax still, I can tell you that there are still many problems with Jax's E that need to be addressed.
's auto attack buffs are NOT consumed if Jax dodges them. Kennen still gets his W auto+Proc, and Shen can still get his %health damage auto. It doesn't do damage while Jax's E is up but it does not consume any of the procs.
It doesn't work on Yasuo's Q every time. It only works about half the time if you're lucky. This one isn't as much of a deal because of how well Jax does against Yasuo.
I'm sure there are more but these are just a few examples. Jax has a lot of bugs with his Counterstrike that need to be fixed.
Also, I've noticed ever since the auto animation changes his auto attacks tend to have a few new bugs, but I haven't tested them out yet so it could be just because I'm bad.
