If I can share just how ive personally dealt with insults and mockery in the chat and its way more effective than I initially thought it would be, also has a calming effect on my own nerves. I still dont always have the patience to reply this way but lately I try to do it every time someone is rude, the usual attacks are: "Damn youre so f-ing slow OMG youre the worst player" along those lines and I reply immediately "Wauw that didnt feel good to read the insults you wrote, youre clearly the better player and play much faster as well, you played really well in the opening hope you enjoy your next game more"
100% of the time this reply gets either no reply or something like "naah youre good bro... gg.."
i dont get replies to that often but when I do It feels so calming and I immediately have focus for the next game no tilt. Try this sometimes but not for effect of opponent but for oneself, very good stuff
I only do that to my friends
