Stealing Roles

days ago i got jung primary , my team mate asked Would u mind if i take jung? yes ..after a while he said i m going jung.. i said dont steal my role but then he locked eve jung (same declared champ of me ) and said i check your history u lost 2 games out of 3 and our sup was supporting her saying its rite like wtf?

first off ,

guys you can check my history i mostly 80% of times i build eve tanky when no one in team tank champ and still in those games my kda was fine ,, even graph tells That i did most of the dmg and took most of the dmg .. What can i do further than this?

And is it legit to steal roles ? its team game we cant win every single game ..

role stealing is a bannable offense

everything is a bannable offence

you took red before blue on lee sin ban you helped your team ward properly ban you died in that team fight but your adc got a penta kill ban you play bot matches ban you qued for fill and got support ban played singed support ban played yasuo...............in general ban didnt ban 4 champs in pick/ban ban

It is frowned upon and a very bad thing to do, but I doubt it is against any specific term.

I mean, if what you said is true, then all games >10 where there's no junglar would all be considered offenses if the top wanted to solo.

Yes, it's punishable, you can only take a role if a person agrees to do it.
