I would give it 5 but certain combos do not flow. Like with jax his quad grapple does not grab opponent at the end of a combo when initiated button sequence, the character lunges forward but never grabs opponent no matter how close and even at times when both characters glitch through each other, jax still does not grapple opponent like they should, to unravel a longer combo utilizing the quad grab.
Usually the quad grab initiates 4 body slams, but when inputted to a combo jax seems to have a non active grasp as he lunges which never lands to initiate a longer combination.
And Jax is kind of slow. Jax needs patches to unlock that quad grab for grappling
