It is going to take a lot of work to fix league
I do not believe anything in League right now can be fixed within a patch. The game is too far messed up for Riot to really fix any of the core issues in one patch, or at least I doubt they can based on recent progression. I firmly believe they probably have no clue what the fuck is wrong in the game down to what should be changed.
That leaves us here to talk about the game. I know the boards have been angry and have lost all temper with Riot Live Design starting with such sheer lack of ability with Ardent Censer and then not even fixing the game at all during the preseason they prepared for in place of fixing Season 7. That's a good thing. The balance team should be held accountable for their failure. Worse, they haven't apologized. How is anyone here supposed to trust them if they don't even display the fact they've made a mistake let alone realize it?
That leads to another issue. Riot not knowing what the problems are means patches don't do anything and Meddler starts talking about buffing Yi and Tryndamere rather than fix real issues like top lane still bleeding even after 7.24b, the imbalance in runes, and lack of viable rune pages for champions. The boards are very, very, very vocal about what are issues. Doesn't matter how well-spoken or rude it is said, people here do speak something about balance. However, Riot made the mistake of not listening to their people, and now these people are angry. Who wouldn't get angry at people with the responsibility to keep the game together that are failing and refusing to listen to any voice, whether it was reason or rage?
Riot shouldn't be surprised their community is angry. Every great revolution in history begins with a ruler who doesn't listen, often careless. Riot is the mother country, the king. It is their responsibility to fix the mess they started. They can start by doing the antithesis to the causation of this: Conversing in real, down to Earth conversation about the game without fear.
I want you to ask someone why they think Yasuo is broken rather than a detailed response that shows professionalism. Have no fear of being mocked for ignorance; draw their opinion from them. Ignore the rage and fire you may face; it is more important to fix this mess than care about being mocked. You can't just have 1 or 2 persons doing this; you must have many people just to prove you are willing to actually converse. Of course, you can't just talk. You must walk! Bring up the discussion of rune imbalance and prove yourself.
Talk with people, not down to people.
is one of the worst champions in the game right now
was the priority
has something to say about that.
or 
because people werent popping you through your passive.
do we still play him just to save allies when they guted his health scaling damage and his ult is absolutely uselss because allies dont listen to pings. because i can play 
and 
(While I know you will argue how unviable this item is on ADCs, it's really not, it's been built on them for a long time as a anti burst item, it doesn't hurt their overall damage enough to make them not want to build it if they have to). Furthermore these two items could be built together and even throw in a 
to help negate some more damage. A build of 
item.
can also be viably subbed in somewhere. Obviously you wouldn't want more then 1 or two of any of these items, but honestly 2 BT/PD are enough to help you survive a burst combo, while BT will fill you back up in time for a basic burst combo (most burst champions need their ult to come close to a 100-0) .
and some HP items. I spose some can use the 
shield but none of that is going to be enough to save you if you don't kill em fast enough. We covered that mages are over tuned with Morello and Liandyrs but if a Mage for whatever reason has to go a different second item, by the time third item Liiandyrs comes in, it's going to be pretty much to late. We throw in supports such as Janna, Lulu and Nami and even at the two item spike Mages lose. (or a tank with Face of the Mountain, Locket, and Knights (or 2 of the 3)
