Maestry level

Hello riot games, It's just say i think maestry point win in losses should be the same than in a defeat or just a bit more: i am trying to level rengar to maestry 5, i am already 4. The last 2 games i played with him where a win and a loss. In the first one, i played very mistaking and ended even with a negative score, hopefully, my yasuo mid was fed so he was able to carry me to win. At the end of the match i saw my champ lvl bar rise a lot, 1300~ points like a 1/7 part of it approximately and i was happy and thinking "wow, i should be able to reach m5 rly fast!". Today i have played a game whic i was always there: i made a lot of kills (31!) and died 10 times, also i stole a dragon and i was responsible of nearly all tower takes. Even though, i had a fiora afk and a troll cassiopeia, which ended somewhat 4/20, he was literally saying in the chat "i am trolling". Finally when we where to end a the enmy team cameback, and they destroyed our nexus. i ONLY gained 233 champ points and the jinx was all the aftermatch time blaming and flaming me. i am so mad and tilted now, because a game i have been carrying the whole time that i lost gave me ONLY 233 champ points. I think it's fair to give more points to the winner, but COME ON! the loser gets like a 10% of the winner, it's not fair at all it would be something if the loser got only 80% and not full champ points, but i thinku give too few champ points for a loss, and with that score -_- i got an S rank.

So just suggesting how the champ points system should improve. Sincerely, A riot games costumer.
