The mentality of the playerbase is pretty damn pathetic
I mean griefing games or just sitting in spawn just because you are behind is not how you become a better player. Everyone seems so keen on just giving up instead of putting in the work to make a comeback. I don't care how large the deficit is, or if you think it's "fun" or not. It's a lot more fun and rewarding to make a comeback and win instead of bitching and moaning in base when you're not deleting every player you see. And no, "I can get into a new game faster" is not a valid counterpoint. You're ruining the experience for other players, plus you agreed to playing to the end in the Summoner's Code (yes, you did when you made your account. Don't even think about denying it). On top of that, who's to say you won't be doing this in the next game when you are unable to delete everyone quickly?
The fact that not only so many players like this exist, but the community itself stands behind this God awful mentality, on top of Riot doing fuck all to combat this behavior is proof that League and the playerbase behind it is the most pathetic community in the world of gaming. Congratulations. I hope you're proud.
