The whole game needs a revert. It would be so much better than this snowball shitfest it is right now.
And yes- that means deleting the champions that should NOT have been released in the first place (Zoe, Pyke, Neeko) as well as reverting some reworks like Galio.
And bringing back the older but BETTER rune **and** mastery systems.
That's all you have to do Riot. It would give the playerbase a sign of trust if you did, not to mention, you really need to stop thinking about your wallets in the first place.
