Yes, he was. Those qualities where pretty much the entirety of Ash's character during XY, and he was admired because people around him lack of those qualities for some reasons, unlike previous series.
It is very obvious that Miette had an interest in Ash, and not only for teasing Serena.
Meanwhile Ash is always heroic, people never put him in an absolute pedestal and never all of the relevant characters are around him prasing Ash for X or Y reason.
Ok, you are a passive person with low confidence. You have a brave, confident friend. You see the qualities you wish to have in him, and you admire him for this. Are you praising him? No.
Your friend is a experienced martial artist, and fights with a master. He loses, of course, but put a good fight. The master compliments him for his skills, even though he lost. Is the master praising him? No.
Your friend fights a friendly fight with a rookie. He obviously wins, and gives some advice. The rookie takes notes from him, because he knows your friend is stronger. Is the rookie praising him? No.
Are you all putting him in a pedestal? No, you all acknowledge his qualities and skills.
No, she hadn't. It's obvious that she was teasing Serena, if you didn't realize this yet, I don't know what to say...
Oh no! The protagonist's qualities are acknowledged by the characters! How dare the writers do something like that!
Satoshi wasn't any more "praised" than the game protagonists, who have everyone around them complimenting their skills, like you said.
It would be praising if he had a fanclub like Shigeru's waiting for him in every town he visited.
Look, I know you guys hate the fact that Satoshi is the protagonist, but you have to get over it, and learn to live with it. He probably won't be replaced anytime soon. And if he is replaced, it will be a boy, not a girl.
