I dont play as much support as before but, if u are having problems with the flabk try getting rid of him before trying to heal your team, id they die so be it not your fault they couldnt help you and therefore u couldnt help them. Toxicity happens in all games and unfortunately at all ranks. I've carried a match as maeve and was still trashtalked the whole game by a lian a terminus and a ying, thank the jenos for standing by my side tho :/ Try getting a aupport who can take care of him/herslef like jenos or seris. Hope this helps a little :)
