YOU don't know which players are good and bad

We all know those toxic people that seem possessed to say something like "you're garbage and should never play X role again" or "Don't play champions you can't play". Meanwhile i'm sitting here having my worst game of the day on a champion i have MASTERED. Am i the best? no. Am i doing well? no. Does this make me bad? NO. EVERYONE has games where they do badly and feed, even challenger and pro players get on board the feed train, feeding or playing badly does not make you bad at the game. The most annoying part is that these games are usually right after you STOMP a game, making their insults feel even more dumb. Not to mention that INSULTING YOUR TEAM HELPS NOTHING, all it does if give you some shallow way to blow off steam for your own self-satisfaction at the cost of your team's performance and morale. Oh and stop calling for ff@20, if you'd stop afk'ing and play the game your team might make a play and turn things around, you're losing what, 20 minutes maybe if you keep playing and lose? How about you use that time to practice and potentially turn the game into a win.
