Please add SOME sort of LP loss reduction when you have an AFK.
There's so many scenarios where AFK's could happen in lower and even higher ELO that it makes a positive winrate harder to achieve. Carrying a 4v5 sure takes skill but it's impractical because that one man makes a huge difference (especially if they are the tank or ADC). I almost have to win 60% of my games just to break EVEN because I know 1 in 5 will likely have someone AFK on my team (hopefully the enemy team).
Here is a system I am proposing: If someone goes AFK on your team and you surrender within 5 - 10 (undecided) minutes of their disconnection, your LP loss will be reduced by 33%. Additionally, the AFK player will take a 33% increase in losses. Note that an AFK before 15 minutes will automatically trigger this surrender at 15 minutes (it's a one-time deal though). The 5 minute window allows for allies to reconnect (for example if your duo partner disconnects you can chat "he/she's having bad connection, he/she will be back on in a bit" so they don't surrender. However a team can't prolong this. For example, if there is an AFK and the ally team was winning, about to win, and after 10 minutes they get aced and are going to lose, they can't just pop an ff just to reduce their LP. It's a risky undertaking if ahead but good to have if behind and then someone ragequits or has to leave early on.
_AFK penalties are also a bit light. By increasing LP loss there's a bigger incentive to stay in the game and try rather than ragequitting. Maybe intentional feeders may rise but the report button is there and maybe Riot would have incentive to look at reports more carefully.
Also if someone is AFK at 7 minutes for example, and the five minute window can't happen, a one-time ff will automatically open at 15 minutes. If voted no, no LP loss reduction will occur.
HOWEVER (added later): If the enemy team has an AFK, you will gain 33% fewer LP upon winning the game (if you still lose then losses are normal). This is to keep it fair. It's much easier to win a 4v5 and getting the same amount of LP means that luck somewhat plays a factor in your games (if they have an AFK then you got lucky and gained some LP for free).
Promos would still count as a loss.
TLDR: AFK's inhibit lower-ELO climbing, as well as further establishing ELO hell. A slight loss of LP when allies are AFK (provided the team surrenders within 5 minutes).
Thank you.
