Nothing you list there was ever earned by her character in any way. Let's just look in broad strokes at her time in Braavos:
All she did in S5 was fail and constantly question and disobey Jaqen to the point that he had to blind her as punishment. She then spends two episodes of S6 on the street, gets beaten up by the Waif a couple times, and Jaqen just shows up like, "OK- you're cool to come back and train again now." Cue up a couple more lost stick fights to the Waif, and, all of a sudden, she's ready for a new contract! Which, she fails to execute, of course.
Next, knowing full well that either the Waif or Jaqen himself will be coming for her, she just goes galavanting around town in broad daylight throwing big bags of money around to book passage out of town. She then allows a stranger to approach her, never even considering that it might be a faceless assassin, gets her belly sliced open from left to right and then stabbed in the abdomen multiple times.
Let's face facts: she's dead. Her character is dumb as a box of rocks at this point. She's constantly failed in her training, questioned Jaqen at every turn and is openly defying the clearly defined rules of an ancient order of fucking assassins that strikes fear in the hearts of everyone on the globe. When Ned was this stupid, he paid for it with his life. When Robb was this stupid, he paid for it with his life. When Jon was this stupid, he paid for it with his life.
Arya? Nah. She's rewarded for being stupid. Based on what we've seen to this point, we have no reason to believe that she'd be anything other than the shittiest faceless assassin in history, but she gets to pass go, collect $200, and become a master assassin because reasons. And Jaqen is totally cool with her thumbing her nose at the Many-Faced God and just doing what she wants, killing who she wants, etc.- also, because reasons. IN the span of a couple episodes, she goes from losing stick fights against a teenage girl to making Frey pies and wiping out entire houses.
I largely liked S6 and thought it was a great turnaround from the lackluster season before it, but Arya's arc in Braavos was a low point throughout for me. That girl's got so much plot armor on her at this point, I can't figure out how she's able to walk.
