Apex arena rating system is broken

I never post anything on the forums or internet but the scoring system of ranked arenas really got me frustrated to the tipping point. 

I like arenas because it really helps you hone battle skills, gun control. situational awareness, movement, positioning and so on. However, in order to progress you need to rank up  and that is absolutely frustrating. 

1) MM has no consistency,  some games you have opponents level 20-30 roll over me and my team with just Boceks. Another time you get Masters opponents that are just laughable and get railroaded in seconds. 

2) RP rewards do not reflect the amount of contribution made by you towards winning. I do not think it is fair to get rewarded 16 RP in Plat 1 for 4K damage ang 8 kills while your teammate made 200 damage and 2 knocks. If you look at regular ranked matches you can still come out on top and progress fairy easily  if you do decent damage and get decent kills. But no matter how hard you try you just cant progress in arenas. I spent 1 week in Plat 1 where you get  +16, +17, +18 for winning  and then -12, -12,- 12 for losing netting you only 15 RP after 4 hours of combat. You need 400 RP just to get to the next level which comes out to 78 hours ( which is like having to work a full time job for 2 weeks). I mean if this was Masters or Pred I would get it, but this is not even diamond rank yet. 

I do hope all these posts will get Respawn's attention and  this gets re-worked tis season.
