To educate the players who might not know.
Riot-tencent couldn't give two fucks about you. They see you as a number and not a human being, one that might spend some money if they just release a few more little legends and skins for Akali. Riot said they wanted to be the most community-driven company in the world and then 2 years later sold 100% of their company to a chinese mega corporation.
I try to bring up issues with the game like Runes reforged because they have done nothing but make the game worse. I try my best to include as much as I can to help someone understand and to read every comment without bias. It's hard though when you get someone with a lukewarm IQ trying to do the equivalent of yell as loud as they can when you are trying to discuss with other people.
