How to deal with these premade?
I was go in a ranked game (solo-ed, since my friends went to the cafeteria) and played ADC with a Sona, Gragas and Velkoz. Before game start, Velkoz picked Jungle and Gragas picked mid and they didnt talk anything to me. Everythings were ok until Sona NEVER go harass enemies, but rather stay behind me (she even flashed 2 times to take 3 kills from me, when I literally 1v2 them from the start). When I talk to her like "Why you didnt use your exhaust?" "Why you are fcking behind me all the time?" All 4 yelled at me, and told me that I will be reported for being toxic - And they even ask enemies team to do that. They even asked me why you think we are premade, and its so funny thanks to op.gg everythings can be figured out in a second. So how to deal with them? Or next time when I see 2 people who pick completely other roles swap champion for each other without any words, I should dodge immediately?
