Nevermind Kabal, Jax does the same exact move with his arm and they made it so he can cancel it. Hopefully this means they'll make Sheeva's cancellable later on too. I agree fully with aedanwolfe too. Specifically with the pokes. I'll take anything to stop pressure.
Is jax ground pound blockable? If someone could master her range and tick throws then alog with smart use of her pokes I think she would surprise a lot of people
