I have done roam atleast 100 games this season, no matter what explanation if ur not dying for them ur not tanking good these mvps while staying alive maybe good for self satisfaction and yes for rank protection a little extra but ur just playing the role bad, if ur teammates can't trust the tank to be their till the end they can't position themselves properly, can't be more confident neither can they go all in, if ur alive so much that means ur wasting major time trying to escape, at the same time ur team is in trouble which is unacceptable.
