How to deal with that type of players ?
I was playing jg and i was doing decent job in early game, i give that twitch a handle of lead by helping him to kill bot lane and get first tower while our top garen was doing good job in zoning daruis and such.
Anyway after level 11 twitch and garen start to trash talk to me all game thinking both of them going to carry, i muted them and moved on so i tried to farm my jg but i found nothing and that cause both of twitch and garen take each camp and clear it even garen took my blue for himself.
So ofcourse by the time everyone was level 18 i was level 15 and hardly got 4 items because they ate all of my farm and while in same time they was still trash talk and even garen asked in all chat "Report that toxic wukong " While both of my mid and support can confirm that i said nothing at all almost all game.
After that we lost game cause we all was ad and i mostly was complete out of game due to level difference and items difference.
Honestly such players won't get banned and i reported them, but i know they won't get banned so i deal with such players ?
