A thought for botlane
I have been reading how all of these players are getting so, so angry at the botlane meta shift, how people think diversity is either bad or still non-existant.
You are outright wrong. We needed a meta shift. The game has spent 7+ years with the ADC/support bot meta. It was getting completely stale, and instead of trying to learn new characters or improving on the ones you already use (because YES, you can counter a double mage botlane if you play correctly. Your playstyle needs a shift, but it can happen), you complain and whine to Riot about how they ruined the lane and the game. No, you are just a petulant brat.
I didn't see you complain when assassins became a common sight mid. This threw midlaners through a hoop, but they adapted. Assassins are the most toxic class in the League. Having the point of a class be "Make one person not able to play the game and assassinate them immediately in a teamfight" is not balanced at all. It is annoying and frustrating seeing a 55 second grey screen when you didn't do anything on the teamfight other than die. BUT, they dealt with it and adapted.
I didn't see you complaining when the tank meta came and then left. I'm sure tank mains felt the same as you did, because many tanks are now next to useless for tanking and are more used for CC and maybe a meat shield. No, they dealt with it and adapted.
I didn't see you complaining when the support roster got flipped on its head with the support nerfs to mana costs and support item nerfs. It hurt the healers and the enchanters a lot compared to what it used to be, but guess what? THEY DEALT WITH IT AND ADAPTED.
So deal with it. You can either try to improve, or get mad at Riot because they are trying to create variation in their 10 year old game. If you want to quit over it, so be it. Not our problem, and Riot has many other laners that will be happy to fill your spot ;)
