Some way to lesser the punishment of unlucky teams

Good day people of Earth,

I've been thinking about this post quite some time now (and I bet there are already some like this) but shouldnt riot find a way to not punish unlucky teams as much as they do? I know its very difficult to do such a thing without loopholes but I really think there should be something like that. Its such a pain to have someone go 0/3 in the first 5 minutes of the game and just go AFK afterwards to end with our team ff15ing and losing the same amount of LP as we always would.

I just really think this is unfair but I personally wouldnt know how to fix this without any loopholes. Do you guys have any ideas?
