Win game lost LP suggestion.

Alright, so my PC crashed at the start of a game and it took a little more then 5 minutes to get back in. I started playing and we were doing really well and ended up destroying the enemy team. The game ended and I lost LP because I wasn't there for 5 minutes. I can understand the reasoning that this is implemented and wont say its wrong. But I didn't like it because I did great that game. I think there should be a voting system from your team, kinda like the honor system. A popup could ask your team members if you deserve the win and they can decide weather or not you deserve LP for the win. Just taking it away was a little cruel. I get that its only one game and if you deserve a higher rank you will get there eventually but I feel like it at the very least it would give the people who crashed a reason to still try to win and not give up because there going lose LP regardless. Just a thought I had in the shower, thx for reading.
