Oh right, because Riot is always correct and have never made any mistakes
I've never said that.
despite your lack of education or professional experience in that field
Why would you bring experience up? It's pretty clear the majority of complaints on boards are from people who are objectively bad at the game.
Or was it your "8" years of anecdotal experience, not at a pro level?
It's 8 years of playing this game at the level which is better than at least 95% of the playerbase. Still, I don't consider myself good enough to rant about balance, yet somehow people on boards do. Truly a mystery.
Abandoning the boards entirely over some bad apples
I disagree. From my POV, it's some good apples and the majority is just whining and crying about Yi, Yasuo and 'damage is too high'. Pretty constructive, yeah.
Riot is not some small time nobody developer that needs to be defended by white knights.
I'm not defending riot, I'm attacking the circlejerking boards. It just so happens that riot arrived at the same conclusion.
No one who works there is going to be reduced to tears over a bunch of people on the internet being "mean" to them,
Pretty weak argument. I never said someone is going to commit suicide because of the message on the boards, but being polite is a must when you communicate with people. There are plenty of examples of how it should be done.
they'd already know that that's just how people online behave
No, it's not. People are perfectly capable of being polite and thoughtful without degrading communication to the level of 4chan shitstorm.
