Taking the Surrender offer when a teammate AFKs will still demote you and leave you with 75 LP

I'm not sure if I am just not remembering this correctly but when a teammate AFKs, you still lose LP but at a lesser amount since Riot's system 'recognizes' the troll teammate and mitigates your loss. So if you were not at 0 LP, you would probably just lose a little LP and off to the next ranked.

But upon forfeiting, I was demoted and still lost the full 25 LP without the mitigated loss. I'm not really complaining, but this is what I observed and I was wondering if this was intended or not.

Plus with the wonky LP gains currently (+14,-17 after a win streak), this honestly just stings and had I known that you still lose 25 LP, I would have at least tried to play the game out and try to have fun with it since I had a really great early game in the jungle.

Don't flame your teammates for doing poorly in lane, there's always a chance to win.
