And here we come up with 2 options: either Jax's design is archaic, or Yasuo's fundamentally trash. I'll lean towards the latter.
Now, see how much difference wording properly does? Anyhow, I personaly think that because of his kit, he'd still be the hypermobile glasscanon he is now. The tankyness would come from a proper shield passive, perhaps he could gain flow through dashes again. Perhaps now flow could be used to empower his attacks as well. There you go, I came up with a "ferocity" like steroid, and he gets to keep his double passive.
The reason why his laning phase is as it is, it's because his doublecrit is taking way too much powerbudget. Lets say, if he didn't have a 100% crit chance with a 250% damage increase, which pretty much means literally all his physical damage is amplified by 250%, he'd actually have stats left that could be allocated somewhere else. Perhaps, that 250% increase, could go to empowered tornadoes when thrown at max flow, or perhaps a shield that procs twice, or perhaps dashes with mixed damage.
Lastly, one more thing. His ult can be popped from the stupidest of things, and his windwall blacks 90% of the game's abilities and 100% of ranged basic attacks. Power budget there as well.
PS. winning the lane/trade randomly(e.g. landing a crit) has never been fun on the recieving end, and doesn't include skill in any way from the broadcasting side.
