Just, remember to use common sense. Always ask for evidence, and when making threads yourself, remember to provide any and all relevant evidence. If you get stomped by a particular champion and then feel like making a thread, find out if the trends actually support your claim that they're overpowered. And if they don't, rethink your view on the matter. Perhaps you could have played better. Perhaps the problem lies not in the champion, but their Keystone. Or perhaps it's neither, and is instead the fault of matchmaking placing you with players of much higher skill. There can be any number of viable explanations, but the one you should accept is the one that's actually supported by the facts.
