Is saying thank you every time you kill your enemy as bad as saying easy every time you kill your ..

I think it's very unsportsmanlike to do either. Whether it's just as bad? I would say yes because you're just being a jerk and a bad winner. I wouldn't want to be on your team even if you were getting the kills because a large number of the people who have BMed in games I've played... they rage when they get outplayed and tilt and end up costing them the game.

I don't see why you would need to say either of those things, and I think both can be interpreted as bragging or being negative, so it probably is punishable if you do it a lot.

Depending on the situation, generally when the enemy makes a move to kill me and I end up killing them instead, I respond with "Fuck you".

I started doing that after playing through Medal of Honor 2010; in the first level, when you get the roof you're standing on blown up by an RPG, and as you get to your feet, one of your squadmates shoves the RPG guy off the roof and follows it up with that quip.

I say it to acknowledge a good fight.

No I don't think it's AS bad... still douchey though.

YES , SAYING CY@ OR EZ OR EZ NOOB OR SOME SHIT LIKE THAT IF YOU KILLED SOMEONE ONCE IS MORE TOXIC THAN SAYING FUCKING NOOB TEAM KYS WHEN YOUR TEAM SCORE IS 0/20 not to mention its a fucking douchebag thing to do , getting tilted and raging in chat to calm down isnt that bad because if your adc has 0/10 you can say they are trash but when you kill someone ONCE and say gg ez noob you tilt them and thats a scumbag thing to do.
