Remakes in ARAM

Why is there no option to remake in aram. I think i play just as many arams as i do summoners rift games and more often than i would like i see afk's on aram. I'm happy that there is an ff at 15 now and super grateful about it but when its 4v5 aram i feel like 95% time its a loss automatically. The only reason i wrote this was because i had 3 afks in a row on aram.
