it doesn't matter how well you're doing or how good of a player you are if you tilt your teammates
if you intentionally tilt them (ping spam during mistakes or even just a bad outcome, unhelpful needling chat, and so on) you are being an overall detriment to the team.
"but they're OBVIOUSLY BOOSTED!" great. whatever. let it go.
"other rare circumstance that happened in my game!" let it go.
I've been behind and unloved by my jungler multiple times. I chill and try to get back into the game as best as my champion allows when behind. treating players like shit does no good. think of your lowest point in league, where you were behind by a large degree, perhaps due to your own mistake. think how it would have felt if someone really tried to hammer how shit you were that game. think if you got berated to the point where you just didn't want to play the game one minute longer.
now think about that before you antagonize a teammate, even if you think they're boosted bronze 5 trash. tell it to yourself, or even shout it out loud. but don't type it (or ping spam it), because you could just end up tilting yourself or your teammates even more.
you'll probably forget about the game within hours anyway.
Tilted teammates is a good sign.
