FILL should lower your MMR for that match

As someone who is flexible and plays every role, I feel like I lost a major advantage when the new dynamic queue arrived. I used to fill so that my teammates had a higher chance of getting their main roles so they could carry more often. With the new system, everyone gets teammates that get to pick their main roles. Unless they picked fill. A player who picks fill shouldn't be considered as familiar with his role than players who choose only 2 roles. Therefore, I think they should be matched in a low MMR game to compensate for this. This also gives a similiar reward to filling players as they used to get in the old system where flexibility means that they need slightly less personal skill in each individual role to climb.

However, the MMR difference shouldn't be too big because otherwise people might abuse the system and pick fill continued by asking for their main role. I don't really think this is a bad thing per se as long as they're willing to play the role that is given whenever they can't trade roles. A side effect of this would also be that people who fill nolong get to play support 95% of the time (as there would be a higher % of players picking fill rather than top/mid/jg/adc.)

Currently, I'm not even picking fill myself. I pick top and jungle because I think I have a slightly better chance at winning with them. I'd like to go fill again, but not when there's absolutely no advantage in doing so other than a shorter queue time. I don't care about queuing 5 minutes if it gives me an advantage. I'm sure many people think the same way which aids the lack of support issue. More people fill means quicker queues for everyone. Not everyone should be forced to fill (if the advantage a filler gets is too great, this would be the case), but there should be SOME incentive!
