since spear of soijon is getting removed is it possible to compensate abit for renekton and jax?

i main jax and this season my peak was diamond3 77 lp on euw since soijon is removed next patch i was wondering if its possible for jax to get grevious wounds like kled because ive mained jax for a long time ever since season7 and there are 2 things that have always frustrated me about him is that number one when im against a matchup that requires me to get grevious wounds like vlad,mundo etc there is no good item he can actually that would match is kit like mortal reminder is just an awful item for a bruiser that needs to be tanky to survive the dive or all in and you might think that well why not build thornmail the thing is its just good on tanks not champs like jax renek you will never see people build them on any champ like irelia,jax,renek etc there are just better items to build and just to remind you if the person chooses not the auto attack when you have bramble vest with champion like vladimir the item wont even work to begin with so i was thinking if jax could get grevious wounds on his W maybe? would help alot to compensate for the removal of spear of soijon and the second thing that is strange is his E

At the end of the duration, Jax Stun icon stuns all nearby enemies for 1 second and deals physical damage to them, increased by 20% for each attack dodged, up to a 100% increase.

not every champion will auto attack and even if they do most of the time people will aa once or maybe 2? but they would never aa like 5 times for real most people would just walk away until its ends instead of auto attacking and i was wondering why not make it armor pen% effect instead of double damage? so that jax wont struggle against armor that hard because if you dont know if you build 1 armor item can you remove alot of damage for example if im playing jax against kennen he builds seekers i litterally dont do damage at all he becomes a tank because jax has nothing in his kit that does %health,magic% or armor% and its just like how do you deal it if you cant do true damage anymore with the keystone its just very hard jax was never that strong in the late game the only reason why it became like this was because of spear of soijon because you could dish out more damage by using more W,Q and even ccing more with his E now that its gone in the preseason i hope jax could get something that could aid him abit against armor ? these are my thoughts as for renekton i dont play him but i feel he will have the same issues as jax when spear is removed. if you dont agree with me when nothing i can do its ok :)
