How to help and fix AD Marksman and current meta

Ok. Riot balance team is literally a joke. 8.11 was one of the stupidest patches I have seen in the 8 years I have played. Hotfixes needed for banner (like they never even play tested the item once) and for yasuo cuz they too gimped to even have easy foresight; even without play testing the stupidity that prevented from seeing these easy foresights is mind-blowing. Hire me or hire someone remotely competent. I get they want to change up metas or shift power to make new strategies and adaptations but some are absolutely mind-numbing dumb or boring.

Anyways besides that point, I am here to inform on how Riot can fix things a bit for short term.

1. Lower critical strike on completed zeal items to 25% from 30% and drop the cost by 100-150 gold. Currently marksman are struggling because they essentially need 3 items to be relevant and it is taking too long to get to that point and fall behind other champions who only need 1 item to blow past them and take too many advantages to comeback. Also 30% critical chance makes NO sense mathematically based on how items work now; this was one of the hugest flawed logics I have seen in a while. Shiv (30%), rapidfire (30%) and Infinity Edge (x2) essentially gives you 120% crit and therefore 20% crit is just flushed down the drain. To have spikes at 50% crit then 100% crit at sooner time frames will allow marksman to keep up with the new meta and be able to get a good core-3 items without being so far behind especially since IE is so expensive and is dead gold until you have at least 1 critical strike item.

2. Static shiv and rapidfire cannon should be restricted to only ranged champions. Like Runaans Hurricane, these items should be changed only to be helpful to ranged champions so things like rengar don't get that static shiv proc for extra burst; this was intended as a wave clear item and for team fight aoe dmg; not additional burst for assassins. Especially good for above suggestions. This would not effect yasuo much other than forcing him to get phantom dancer (maybe make a new crit item that's more for melee?) as shiv is a reason why he is too strong with easy clear potential. Other melee champions should not have the privilege to get the chance to crit more often than 50% if they so choose and should rely more on better base values and better scaling abilities. Only person that would be affected greatly in a negative way is tryndamere but he really is overdue for an adjust imo anyways (mainly to passive and mocking shout) especially since he has not changed much compared to most champions yet he is one of longest tenured.

3. Nerf Master Yi. Double strike passive is bonkers with new items; alpha-strike having lower cooldown on autos makes attack-speed way too optimal especially when he already gets assistance from his "E" ability.

4. Nunu is boring and not doing well or doing way too well so is hard to balance. He needs a huge adjust as his passive sucks and his bloodboil is not interactive at all. Perhaps even an overhaul/rework is needed. This is more long-term though.

Bump so a Riot employee sees pretty obvious flaws they have and can make relatively easy short-term changes. Also so I can get a better job than working minimum wage customer service at a lame company for a product I don't think is that great.
