Isn't this just dismal, you get downvoted for making fun of how the community downvotes everything. Classic. At least you're pointing out something really unfortunate about the boards.
First of all, the behavior system doesn't need to be fixed. I could care less if the abominations I play with get banned or not, I'm satisfied with being able to mute them and completely disregard their existence; if only I could mute pings I would be happy.
Secondarily, voice chat I actually wouldn't mind honestly. Having my chat swamped with cursing is annoying, I'd rather have it occur in the voice chat, then just mute them all so I can play a peaceful game.
Third, do you actually think people on the boards represent any sort of community? Aside from a few noble heroes (Malicious Metal, Melledoneus, Mira Arya Enthe, many others I'm forgetting that actually share good ideas regarding champions and write well), nobody on here even has a moral compass, and is likely under the age of 13 (thus not even meant to be playing this game). I think everyone has great ideas, but this is not the place to post them. Reddit seems to always have red responses on it anyways, and I'm pretty sure Reddit doesn't have a "community" as abhorrent as the cringe we witness on here seemingly everyday.
