Most useful feature in the game:
The mute button.
Yeah, I know, don't bother telling me this thread has been said thousands of times. Well I hope it's repeated a thousand more if it gets the message across.
For every 100 people that complain about how bad the community is, maybe 5 of them use the mute feature. Do you realize how fun it actually is? To know that there's another human being, a very sad, miserable little human being who is very angry at something that doesn't really matter, and no matter what they do you can't hear them?
If someone starts flaming my teammate, I usually don't mute them, I try to settle the dispute. But if someone is constantly "gg surrender @ 20" "Why haven't we surrendered" And then CONSTANT blame to his/her teammates, whether or not it IS their teammates fault ... Mute.
Don't say anything, just open up the scoreboard and push that little magical button.
I'm being dead serious when I say that 2+ minutes later, I completely forgot they were pieces of shit and I muted them in the first place. The only reason I remember is because one my teammates will say something random, out of the blue, and it takes me a second to realize I muted the toxic-anchor our team was carrying around.
When you are constantly arguing or flaming, it's like texting and driving. Half your brain isn't on the game, it's on this petty argument over blue buff or minion tax.
Please, I'm just asking that next time you run into that negative nancy, mute them. It does MUCH more good than you think it does.
