Experiencing an unwinnable Ranked Game, and What to do about it

So today at about 6 AM, I was about to head to sleep, but I wanted to run a quick ranked game. I joined in and there was this man (unnamed for boards terms and services) who claimed he could only mid, or jg. I have seen people like this before, and believe me, I am the first person to dodge to avoid MMR Damage. Well this guy could only do 2 lanes, but the problem is, we have a jg main and a mid main on our team, and they were bot higher pick priority (he was last pick, I was second to last). They pick his lanes, and I go AD Carry, and am stuck with an inexperienced support. This guy goes Lux, after asked to play a tank.

I tried not to get angry about champ select, but in game, even the calmest of players would get salty in their own way. Our lane was a Lucian, Lux, Versus a Jinx, Blitzcrank. This lane is very easy for a lucian, as I have played against it close to 50 times. The game started out good, I hit my cs quota, (80 at 10 minutes) and was just farming. Lux on the other hand was sitting there snaring blitzcrank repeatedly. I had no issue with this, because i could just keep on farming, but the one thing i had told her was to not get pulled. I explicitly said "Keep it a passive farm lane, while i deliver poke, and DO NOT GET PULLED".

I have never seen a person with sidestep skills this horrendous, she got pulled 4 times in a row, each of them instant death. I asked her to go mid but she stayed bot and continued to do this. She fed all game, and contributed NOTHING. (I am not Ranting she went 0/10/0 Look at my recent games)

Honestly the only way to deal with people who can only go one lane, and are terrorists about it, (when i say this I mean like they pick a mid laner for like jungle or something.) is to dodge. You lose 3 LP and don't ruin your MMR based on other people's actions. Hope this article Helped.
