The game is in a pretty shitty state right now

AD itemization far outclasses AP period. It has better build paths, better items, better starting items, and to top it off AP items got nerfed mostly so that full build AP builds often contain about 50 less AP even though void staff gives 80 now (most AP builds yielded around 750 AP full build on average now we hit about 680-700). We lost 20 on Luden's, 20 on Zhonya's, Also AD has a better diversity to choose from (it's always been that way but at least mages had really good gold efficiency). Also I want to mention that has almost the same gold efficieny as while and have near the same gold efficiency but enhance more attributes.

There is way too much damage and unreliable sources of it in this game. Masteries added a huge chunk of DPS to almost everyone not even including keystones. Without keystones we get about 5% more than last season. We need to tone all the keystones down. Move everything backwards because the games are going way too fast with basically everyone having a 5th ability to scale off of causing rampant snowballing (hence the reason Thunderlord's needed to be nerfed, not the other masteries being buffed).

Let's also not forget that Riot has still yet to fix the core items that are breaking the game right now: (its a mana CDR item that is being built by non-mana heavy crit ADCs but it was made for casters) (still havent dealt with the ridiculous gold efficiency combined with income and high utility benefits.).

There is no way to play safe while behind because you cannot buy any form of vision that will last if you are behind. Meaning that one kill can lead to complete loss of lane and results in the end of a game because it is often less dangerous to face check or roam while ahead than behind. Simple solution is to at least let us buy green wards again and maybe redo the blue trinket so its not gambling for vision when behind.

This season is just so shitty that I literally can not enjoy playing it by myself anymore. I have to play with friends and do weird non meta stuff all the time or I feel A) bored because every game is the same thing (I mean it was before but at least it didn't feel like every game was just a bunch of people nuking eachother 24/7) or B) pissed off by how many toxic mechanics are now in place thanks to S6 changes.
