There have been many a time that I have contemplated scratching that itch - but I have placated it mostly with Tree of Savior. ToS is a game being made by most of the original team behind Ragnarok Online.
Tree of Savior is in closed beta now in Korea, maybe we'll see a CBT for the international version by the end of the year. It has been picked up by Korean Nexon, maybe NA Nexon will also get it, but that usually isn't a good thing.
Also, that guild introduction package is all sorts of broken.
