All the high defensive and powerfull Ability Have 20 + cd except for jax Counter strike being 16 ?

Im gona give Few exmpl Before start argument. parry 26 seconde, Wind wall 25 seconde, arcane Shift 25 seconde, Living shadow or rather known for his w 22seconde, Black Shield 26 seconde, W 23 seconde, ... Etc Lets talk about Jax counter strike or his E rightnow, It give him 25 % damage reduction, Block auto attacks for minimum of 2 seconde duration, Does aoe stun and Does some good damage reach to 300 base and That damage can be increase If u attack him While he's using it, Idk about anyone and But for me personnaly this's honesly the most overloaded Ability in game and its on fuking 16 seconde cooldown rank 1 and its Goes upto 8 seconde at full max... That mean with 40 % cdr and active , the most powerfull Spell in game is on 3 seconde cooldown And Can run to ur entire team and kill u with no counterplay Because u cant heart him Inleas u are mage. So can we Please jax E either nerf the Cooldown making it 20 seconde + or Just rework at this point because its such overloaded ability and So broken and unfun to face and even with removal of , Will remain overpower because of how free to get 40 % cdr rightnow
