A while back I was playing support in ranked and got into a fight with my ADC
Our team was Jinx and Renata The enemy was Kai'Sa and Tahm Kench
Laning phase started off well, our Jinx picked up a kill
But I was thinking, "Even if we go even here, we'll be stronger later anyway, and Renata's autos do fuck-all damage, so if I try to poke Tahm Kench for no reason and fuck up, we're screwed. Let's just farm minions and slow push." So I didn't go all in
My ADC was thinking, "We're both ranged, we should play aggressive."
With that clash in playstyle, we had a few mishaps here and there, and top side was getting absolutely gapped, so we were both tilted and started bickering
Things got heated and the other guy dropped his number saying to call him, and I was so pissed I called him right away
But instead of jumping straight into insults and fighting, we calmly talked through our sides of the story, and came to the conclusion of, "Well, we lost because of top lane anyway. It's a top gap." So we wrapped it up telling each other to play well and moved on
If he had started hurling insults, I was ready to pull out every fucking insult I've heard playing League, but since he ended up talking calmly, I didn't bother getting mad either
