Pls Riot I Beg You, Some Type Of Less LP Loss When Team Has AFKs

Seriously just lost a very winnable game vs a team with no ADC,,,they had 3 ap champs and 2 tanks. When our team was together we smashed them each team fight....which was both times, because for some reason apparently it took 3 of our members at least 5 minutes to buy a damn item.

3 members multiple times each spending long periods of time at the fountain. Then would go back playing like nothings wrong. Only 1 of them even tried to give a reason for their multiple times afk and she said she DCed even tho the game never said she DCed. But what are the odds that everytime you go base you DC?? Come on now.

Late game we couldnt even contest dragon or Baron because someone was always sitting at the fountain...other team got both and pushed to win. 2 of us did not deserve a 22 LP loss when in fact we should of won the game.....our last time having full team we pushed 3 towers and inhibitor...then we went base and our top never left fountain after that.

There has to be a system in place to sense afks and not give all full LP loss to the other members and a counter measure in place to keep premades from abusing it.
