I know this thread will be full of chill guys that never nothing gets to them, never can be tilted etc but I would like to talk about how tipping is really most toxic thing in Dota2. It doesn't even serve any purpose other that aknowledging you try to convey your opinion on ther's play, whether it was a bad play or good. Speaking of which, tipping most of the time is used to troll other player that either made a bad play, died, etc, doesn't even have to be their fault to receive a tip that is supposed to make them tilt.
I would not even have second thought about this stupid feature if not for a fact that it can't be turned off, at least you can turn off communications if players behave badly, but tipping is there for anyone regardless. And I know some will say "it never affects me", but the truth is tipping will always alter your game to some degree, and imo mind games like these should not be allowed in Dota2 since game itself can be a mindfuck itself sometimes.
