Well if you do something that doesnt make sense and do what everyone can do it is fustrating. I mean honestly if you carry while playing tank shaco and one shot squishies it feels unfair and stupid for the person on the other screen. Also Honestly being salty is kinda normal when something doesnt go their way.
Also rubbing the comment "salty" in their face is really Annoying honestly it makes you look like the asshole in the story
When someone plays Fizz and I kill them as mid Sona I think I've earned the ability to enjoy the salt
