You are of course right, the ranked arenas is broke and has been since it came out. For the current season I have heard of people winning all of their placement matches with good kill and damage counts and getting placed in Bronze 4. while others have gone 5W/5L or 7W/3L and placed in silver or higher. That is the first thing broken.
The totally arbitrary awarding of AP is also broken and no matter how well a single player does if their random teammates let them down or cause a loss their is no reward just loss of AP. this has happened to me get 9 kills and over 3k dmg and loss the match because one can not carry all the weight while your teammates combine for 3 kills and less than 1k damage.
The best thing to do as a player at this point is to use arena's as a better firing range to warm up and then move on to duo's, Pub BR or ranked BR.
