This just happened
I was playing as Kat. I was 4 man ganked and Udyr died instantly. While they were chasing me they were all in basic attack range and i was low enough to die. If I kept running I was gonna die either way to might aswell go out in style so i went in a E'd and the obvious happened.
Udyr started flaming me.
I went bot 2 times later and successfully ganked with Sona ksing 2 kills
Later Udyr kept flaming and got Sona to flame me too with the line "The supp has more kills than you" and kept saying i was bad
After she said that I got an ez triple under turret then decided to flaming me saying you waiting till their hp was low.
I replied "I poked them with my q the whole time" then she decided to poke at the fact my ult was canceled saying I just wanted it show it off.
I got another triple at top. Vi was losing lane so I went up top and saved her. She got away will abrely any HP follwed by a missed jinx ult.
I said "Yw Vi" she told me to shut up. Then sona replied with "Dont worry vi she just wants to show off" Keep inmind these 3 are in the same clan and most of them played only bot matches.
I reported all 3 of them after each of them fed hard in the end. I couldnt carry this team.
They are the reason League of Legends has a salty community
