Forcing people to dodge
Theres nothing worse than see someone was autofilled, and locked evelynn with cleanse and ghost, without saying a word. Thats pretty much forcing people to dodge so you dont need to support. I just had to Dodge game like that on last second, and not fun to lose 3 lp and waste like 15 min because of some clown cant play support once in 10 games. He could Dodge himself or ask if someone can swap roles, if there is no way he cant play one game support. But I see that as extremely toxic behavior and it should be reportable somehow. Feels worse than if someone calls you noob in game...
