Should there be a harsher, faster sanction on saying easy / izi / EZ ?
I think so, and here's my point.
Pure toxicity is not that common (1 player ou of 20 maybe ? Wich still means 1 or 2 game out of 4. )
However "EZ" seems to be much more common. I think at least 1 or 2 people will say it in ANY game. I know of some players in my friendlist that use it pretty much every time they win, and don't seem to be sanctioned ever. ( I tell them to stop, but they don't care, and I have to admit they're still fun to play with, as buddy.)
EZ, although technically frowned upon, is tolerated.
However EZ seems to me much more toxic than one would think. It's the little mark of disrespect, the little casual spit in the face of the defeated foe that won't do much, but shows that you hope he is raging. It's like the essence of unspormanship, not because it's that horrible, but because it serves no other purpose than being a dick for it's own sake. In fact, that's why I find it even worse than raging. Rage can happen during a game, you're nervous and you say things you don't mean ... you shouldn't but there's a reason for that. You're feelng bad yourself, you don't enjoy raging.
But EZ ? EZ is a calm and delibrate choice to be disrespectfull. It's not lack of self-control, it's choosing to be unpleasant because you enjoy making people feel inferior. It might not work taht well, but that's what one tries to do with EZ. That's the ONLY reason to say it.
For that reason, I would love for it to be really sanctionned. I'd like people to get warned for this, explicitely so that they actually stop.
