One of the last interviews recently to ask Yoshida about parsers, to which a friend was one of the lucky few to be present, he said Yoshida's face went serious and said, in firm English, "No." That same friend wants in game parsers and he pretty much said, yeah, we're not going to get them just from how Yoshida answered, it's beating a dead horse.
Also, the in game culture stuff you quote is stuff not supported by SE. If it ever interfered with SE's business, they'd ban it. As it is with parsers; you get caught talking about it in game and get reported, you get suspended.
Right now, Yoshida's stance is very anti- parser.
Honestly, I'd sooner adopt the JP style of things: if you can't clear the content after so many tries, disband. It's not like I could help someone improve if they play a class I'm not good at, so even if I wanted to help them, I couldn't. However, I also don't want my own time wasted. Just appeals to me as it doesn't break ToS and my own time wasn't wasted.
