New positional ranking encourages throwing/griefing/trolling more than ever

With the new positional ranking system, I’ve found that more often than not people are throwing games because they didn’t get their main role and aren’t losing/gaining a substantial amount of LP. I see two solutions to this (maybe there are more, these are just the ones I thought of).

1: increase queue times to lessen chance of autofill occurring. Pretty self explanatory.

2: increase the amount of LP loss/gain in other roles. If you increase the bleed effect of LP, people will have more initiative to try to win. As it stands currently (at least from my personal experience), you only gain or lose 3 LP max in other roles per game. I think this amount is far too low to have an impact on anything.
