I don't see mass bad play, and the only time I had to abandon a casual duty was rab and royal menagerie when they were brand new..

See what you wrote there? You abondon shinryu NM since people couldn't handle it. That alone is bad in the first place and also a indicator that Square enix has a minimal gap between story trials and dungeons, then a huge one for people when a decent extreme comes out. Hell people even failed a lot on susano extreme when it was new too, which was pulled 2 times and I got it down. And if you really say you don't see mass bad play then look at your own text again. There are plenty of bad players in this game, far too many for easy content.
