1. **Champion Mastery Emote**
I'm sure RIOT had a good intention when making the Champion Mastery Emote for players to show off their mastery level, but what they either didn't realise or refused to accept is that people use it for BM-ing above anything else, it doesn't belong in a game where you're supposed to be humble in victory and graceful in defeat, sorta defeats your logic and moto, doesn't it?
2. **Fear of the community backlash when proposing certain champion reworks and changes**
Yes, I'm looking at Lee Sin, Thresh, Rengar and so on, the favorites of RIOT Games, their love children, the apples of their eyes... I understand you don't want the community to hate you for changing their favorite champion into something different or making them a bit weaker since they are pretty damn strong at that moment. But you choose to accept that the champions are too strong and oppressive instead of making them healthy and getting heat from the players. It all comes back to money, right?
3. **Players who say Lane Open and then refuse to play any longer**
I understand that you're a dumb monkey who can't handle their emotions like a normal person, but don't take it out on the rest of the players, you're wasting my time and my team's time, players like that should be paremently banned. Go play with LEGOs, if you can't handle losing like a man/woman.
Add things that you started to hate about this game, just let it out...
