This forum community as a whole needs some tweaking. Yeah this community has downvote fairies like any other community, but we also seem to have people throwing about upvotes unnecessarily to replies that already have plenty. In a thread forever ago when a Rioter asked in so many words, "Why do you as a forum-goer upvote or downvote posts?" The most upvoted response was more or less, "I upvote things that promote discussion, not necessarily whether or not I agree with it. I downvote things that don't promote discussion, not necessarily whether I disagree with it." Yeah... sure.

On paper, that's a great view to have. In reality, the top discussion in any given thread is people dogpiling downvotes on someone (and all of their subsequent posts on that thread unless they include the word "sorry") and upvoting everyone that responds to the person saying otherwise. I don't want to have to click "show comment" on something that apparently sparked a ton of discussion on half the posts I visit. I don't want people upvoting replies like "You call him bronze but you're just silver 5", because that adds nothing to the discussion of the topic. If you want to downvote somebody that has both an incorrect view and genuinely deserves to be downvoted, then do that without upvoting the other replies so much and making that discussion chain the top one. If they genuinely aren't promoting discussion, stop moving their voice to the top of the thread.
Usually within 3 replies to the main discussion there will be an upvoted overused joke that, once again, adds nothing to the discussion. If it were in the Memes and Games section that'd be fine, but saying "How can Lee Sin be OP if he's always cc'd by a blind?" adds nothing to the discussion and should be downvoted (or at most stay at the default 1 point mark). There's usually a reply somewhere in popular threads that says "I agree", "^", "You're so right", or "*You're", none of those add to the discussion and do nothing productive unless you're a heavily influential figure in the League community adding your ethos to the discussion, and even then you should use your reputation to be a positive influence by explaining why you agree.
