Only sarcastically, when that's really obvious.

I think it's ok in team chat, but I wouldn't say it in all chat.

Only ggs for me, League is better when everyone isn’t being a jerk about it imo. I always report the people saying ‘ez’ after a win, even if they’re on my team. Not for the people doing it in jest though lol

No it's toxic imo

People who write “ez” play the game to boost their egos. I usually never type and never flame. I would sigh in real life rather and mute flamers
