LP for Ranked AFK Forfeit/Remakes (read)

With the current system, when a player is afk or does not connect in the beginning of a ranked game the team can forfeit at the 3 minute mark and the game is remade. It is my understanding the afk/unconnected player loses LP for whatever caused the inconvenience, and the opposing team gets nothing for their time.

There needs to be compensation to some degree for the time of the players in a ranked game. Between queue, champ select, load screen, and those 3 minutes waiting to forfeit (where sometimes the 5 man team can be ahead a kill or two), all players are anywhere from 15-20 minutes invested in the game, maybe 20% of the total time that it takes to play a game. In the old system teams with an afk player in a ranked game played the 4v5, typically lost, and everyone's LP was adjusted accordingly.

I propose all members of the 5 man team who did not forfeit should receive a SLIGHT LP reward for a win in an 4v5 ranked match that forfeits. Maybe 20% of the normal LP for a win (2-3) points, literally anything that will compensate the players for their time and fortune. The previous system caused significant headache in the virtual rankings setting, the new system causes a headache for players in real time/real life where they are now wasting time and commitment for nothing.

Please assess, and let me know what you think. Thanks

EDIT: To clarify, the 20% LP is for the winning team, the 5 man team. In the old system this team used to flat out get the win. The 4 man team had to play with the afk player. The new system should compensate for 20% of the old system. Given the time, commitment, and tradition of preserving the competitive balance.
