People misunderstood "GG EZ" and "REKT" ?

Oh I definitely agree with you on that one. I'm actually really nice with people who just aren't doing well but aren't toxic about it. At most I give some advice. Putting them down doesn't do anything.
The worst that can happen is that they don't see the difference between constructive advice and criticism (or are tilting themselves already), but it's really their thing at that point, not much I can do about that.

The only people I'm ever a **** to are those who play horribly and blame others for their mistakes. That's the only moment where I feel like the guy needs to be reminded that the 3 kills of his 3-12 KDA are because of good ganks from his supports...
(the thing is, that's 95% of players right there)

Yup ahah I see your pain. I had recently a bad encounter with a jungle Legion Commander of that sort, where I was a Slark that was actually doing ok and tried to tell her nicely to properly initiate fights and things of the sort so she started flaming me for 1) "being 10-2 or whatever and not carrying me" (wutface); b) Playing Slark because "only jerk people do" and 3) finally, my favourite: "You suck because you're playing a hero that you press R and you win".

To this day, I'm still wondering if she mistaked me for Zeus... :)

When we won, I just type good game, better luck next... if enemies won, I type GG WP.

As far as I know, it's a tradition that any hour-long or longer game must be finished with a 'gg ez' by the winning side. It's just how things are done around here.

I just say gg wp in all chat whatever be the case and tend to not flame anyone unless that person is being a total ****.

I am smacktalker, skywalker, and I got a mike saver for a hater. I trash talk, I troll, I don't care about anything. Why? Because when people blame you for their mistakes, they need to constantly be reminded that they are the ones that makde them, because "they are new to this game"

If people understand, they won't flame back and laugh it off or play along, if they don't, they're probably going to flame back and all.

I never used "rekt" or "ez". I am usually typing "gg wp" followed by ">Good game, well played!" from chat wheel.

I very rarely use "offensive gg". By that I mean when I am typing "gg" when my win isn't 100% sure. Many people are typing gg just after taking 1 set of rax and they are backing off. For me it's just rude. I am also not a fan of using ">Good game, well played!" when I/teammate/enemy makes mistake or dies.

I use offensive gg when my opponents are salty/unpausing when someone is out and he is trying his best to come back/using abusive language.

I also type "gg" when we have megacreeps/they have no buybacks on crucial heroes - when the game is practically over. I remember once I lost a game when we had megacreeps against them, I typed "gg" and I lost this game. Shame.

Shame.
