afk in rank need a better solution

there a problem with this game allot of us serious players work hard and spend allot of money on this game now ive had a few afk's in rank not just people rage quitting but from the start of the game was wondering why there wasn't a 5 min or 10 min surrender option were no one loses lp if there a afk from start of game. its not fair to all us working hard to lose lp for that just putting them in lower q dosnt help at all my room mate is a big afker and hes had to do that many times dosnt stop him from doing his 5 game then pissing people off going afk next time hes a idiot for doing that ive tried to stop him bit he wont listen to me (why i dont play games with him ever) but why are we losing lp for others being afk im not talking about a rager who leaves 20 min into game im talking about a afk from start there should be a vote option to stop game 5 or so mins in with no lp loss or something we shouldnt be having to fight 4 vs 5 it ruins the game and if we do no way that should be a lp loss just cause we have a afk isnt grounds enough to punish us people trying to play and climb
