4v5's are not just "some disadvantage"
They ruin the game outright.
One side is nearly guarunteed to win, where the other has to slog through at least 20 minutes of pointless fights, which is elongated if anyone on your team is the "never surrender" type of person.
With the new client, there are a few things I want in this regard.
- A ping display in client.
To reduce the frequency of lag induced afk's. If a player KNOWS that their connection is beyond shit at the moment, they will be less likely to go into game.
- Safe to leave games
If a player disconnects for at least 3 minutes, other people can leave the game without penalty.
- No LP reduction
If a player disconnects for long enough to trigger the "safe to leave" condition, no other player will be penalized for the loss.
At first glance, that last one seems like something that can be abused by premades. "Oh, every lane lost. Eric, your turn to take the burden." So that the LP lost is minimized.
The thing is, if they just took turns afking to not lose LP, their accounts would quickly get banned, negating their efforts. Even if they had one person play the scapegoat and take every loss, they would need an inexhaustible supply of level 30 smurfs to keep their scapegoat in the game, which would just not be worth the time or effort.
