Whose at fault here?
So me and my friend just played a game where we went bot lane, as soon as my friend hit level 4 he decided to go mid (yes he told me he was) he successfully got the mid laner first blood, which is really good. At the same time this is happening I'm left 2v1 against karma and morgana, they started to close in on me so i backed off, out of no where karma shields herself for that movespeed bonus and manages to stun me after which morgana stuns me followed by karma stunning me again, which of course i die. My friend then proceeds to flame me even though there was nothing i could do. I told him i died partly because he left me 2v1 against strong champs like that he instantly denies it and says it my fault. All i want to know is whose fault is it really? If it truly was my fault then i have to accept that.
