Suggestion to give bonus depending on your Solo/Both/Team Category

Actually I had a suggestion to add "Don't match me with premades" and "Break our premade team when set time limit is exceeded" options when creating games. But I fear it won't happen. I also know similar feature already exists but it's calculated based on current match and not player queue type preferences.

So here is a suggestion on how to make new player categorization feel somewhat helpful.

Overview. Give bonus LP when player gets in game associated with his current category. For solo players - give bonus LP when solo player gets into a game with premades. For team players - give bonus LP depending on the size of player's premade team. This won't solve the problem with solo players being forced into games with premades but at least it will give some nice bonus.

Details and examples. Solo. You receive LP bonus when you queue as solo and get into game with premade teams. Bonus size depends on size of premade group in your team: 4 premade: +5LP, 3 premade: +4LP, 2 premade: +2LP (applied once in case of 2+2+1). Bonus applies whether you win (more LP gain) or loose (less LP loose). Team. You receive LP bonus when you queue as team. Bonus size depends on size of your premade: team of 5: +4LP, team of 4: +3LP, team of 3: +2LP, team of 2: no bonus. Bonus applies only on wins. Solo&Team category. No bonus.

I think it be better if bonus would not be flat but rather calculated as a percentage of final LP value or be drawn from a table based on elo rank and MMR. I also don't really like the idea of rewarding LP for the fact of being solo or premade and for skill but since there is a problem with playing in and versus premades and since LoL is a team game - it may not be as bad.
