Having expectations of a teammate is not toxic
I keep getting in games called toxic and other teammates being labeled as such for simply point out facts and holding expectations in the game.
For example, Top lane Darius is moving down to the mid lane, top lane pings several mias and a warning on mid. I'm jungle and I'm in bot side jung, too far away to effect the situation. So I ping as well.
20 seconds later "AN ALLY HAS BEEN SLAIN"
Mid laner just died... even though we both warned him.
I said in chat "Did you not see all our pings?"
Our mid and support "OMG YOU'RE SO TOXIC WTF, YOUR MOM DROPPED YOU ON YOUR HEAD. etc. etc."
It just seems like people don't seem to understand what toxicity really is and use it as a get out of jail free card when someone criticizes their play.
TL;DR: Expecting people to react to pings and warnings in game is not toxic.
