Why Provisionals? Just to frustrate us!

I had a bad season last year, started in Silver V and dropped all the way to Bronze V. It was a combination of a lot of things. I think what hurts me most is that I am mainly a support person. That is my makeup and I know it so my kda is always low (not good). So when I get a win I earn 1o points but when I lose a match I lose 20 pts. The preseason was the worse because nobody cared and I lost so many games due to this. But on to main point:

I though new season I will see how provisional go. I competed in provisional and won 8 out 10 games. I was in with people that cared to competed and win by teamwork. It was really fun. The I finished the last game as Morgana went 0/4/28 and received the message "Congratulations you have been awared Bronze V". After ten games I was right back where I ended last season and didn't even get the IP points earned during provisional. Sorry but this is a truly bad system. It rewards ks and punishes the support player. I am not sure but think I might be done with ranked play because just don't see the point as a support player.

Just sounding off some frustration.
