Honestly the fact that ARR was made off the broken husk of 1.0 is really all you need to know in regards to why they're constantly shooting down suggestions. 1.0 was for lack of a better phrase, strung together with bits of gum and string, and barely functional by most MMO standards. The coding was shit, the methodologies absolutely nonsensical if you care to ask someone versed in programming, and overall it showed that SE really had no idea what they were doing in spite of having a previous MMO under their belt to learn from. People are not kidding when they say that in order to fix all these issues they would literally have to create an entirely new engine and start from scratch, and frankly it might very well eventually come to that as more and more limitations are pushed against with each new expansion. Yet I'd be amazed if it was ever implemented before the eleventh hour, as Japanese businesses are /not/ known for overhauls when what is currently being used has /some/ functionality. And I don't think it's necessarily fair to lambaste Yoshi P for that either, as ultimately the ones who hold the funding for a new engine are the board of directors at SE itself.
