How to balance the game

Dear Riot: Lol is a game for skilled players, or at least it was, the players that had more control of the champions and more knowledge of the game itself would scale in game more easily and progride faster in rank. Today things are a little bit different, the game has become bigger with more champions and more itens to study and know about, not hard to understand to those who play the game frequently and to those that like to make an effort to be informed of current changes, but to others it became a big mess with lots of headache, also the community has become huge and impossible to control, due to all this, the game has become harder to balance for riot, mainly in match making. It has been very hard to get balanced teams, mainly in rank, it is very unfair to players that want to play the game and try to do it well, have to be in a team where are unskilled ones, that go to rank playing champions for the first time, that the game is not going to well for them and they put the blame on their team mates and start to flame, trolling or go afk, among other bad things... Well i think Riot can do more, so i leave here my humble suggestions for match balance:

To start no player should be allowed to go to a ranked game with a champion that he is playing for the first time, it should have at least mastery level 3 or above, with that champion to enter a ranked game. Players who play well should be always rewarded even when they are doomed to be in poor teams, so riot could implement a MVP (Most Valuable Player) system in ranked games, should not be hard since it has already the classification in the end of the game with a scale from C to S+. MVP? How should it work? In my opinion, there should be an MVP on each team, (and) (or) a MVP of the game.

The MVP of the defeated team should not lose any league points or at least lose a lot less than usual, this would make that players try harder to play well even when they see that the game is probably lost, i think beside compensating better players it would bring less trolls and less afk's.

The MVP of the winning team should be compensated too, with more league points, or more IP points (Blue essence, next season), or loot itens.

Hope this opinion can help...
