Honestly the only way to actually have fun playing this game..
Is pretty much to mute everyone, and just play the game. Since if you literally say anything in all chat or on boards you will have people downvote you just because they felt personally attacked by something that you said, that is in no way toxic or offending to their main champ (often the case).
I just accepted the fact that it's impossible to reason with most people in this gaming community. My goal is to potentially move on one day and quit this game like the many others have done so already (Dyrus and NB3).
