Ranked Role Assignment System Bug

(Above is the match where everything I'm describing occurred.)

So this player LAN GRIMM LFT got auto-filled jungle. This player asked to swap for ADC, and I hovered Draven. He banned my champion and forced me to play jungle, I had no option to dodge because this was the 5th game of my diamond 4 promos, so I decided that I would just play jungle and a loss would thus not affect my ADC promos.

As last pick, this player picked Nocturne and went jungle. We lost the game and I lost my ADC promos, while the player who forced me to jungle, lost in his off role (jungle), even though we both played jungle, I got assigned ADC, the troll got assigned jungle.

I'm posting on the boards because Riot support won't give me any LP back, even though I had to play another several more games to get into diamond 4.

The long and the short of this is, there are certain situations where the system might unfairly assign players roles at the end of the game.

Player A gets role A Player B gets role B but his main role is role A Player B forces Player A to swap roles.

Player A picks a champion for role B, Player B sees that the matchups are unfavorable, so he also picks a champion for role B.

This allows Player B to lose LP in his off-role, instead of his main role, while Player A is forced to play double-jungle and lose LP in his main role.

To remedy this issue, I have two simple solutions.

1.) Disable autofill completely (autofill sacrifices match quality for queue times), For the vast majority of players autofill is a bigger problem than queue times.

2.)Create an option for players to trade positions, (similar to how players can trade champions). This guarantees that when someone agrees to a swap, they can't back out after champions are picked.

At the end of the game, the system that detects swaps would still be active, but if 2 players end up in the jungle, role swaps at the beginning of the game would decide who loses LP in what role, instead of original roles.
