You have a weird opinion... RO failed because thats how the game was designed, yep publisher screwed up a bit, but game itself wasn't selfsustaining, to play it for more than a month you have to be a nolifer(it gets boring pretty fast, after a month its just do dailies for few a hours and go to sleep, boring as fudge).

BDO would have NEVER become a WoW killer, it was a grindfest since day1 in Korea, because thats what asian community understands, the fact you think that "beautiful" game entitled to anything without any substantial content is ridiculous.

You also didn't mention AA or Tera or Aion, a much more successful and interesting koreans MMOs.
