Letter From the Producer IX.

[Gramul]

What's the fun in that if battle is still messed up >.>

They're working on that too. Did you just forget about the last letter and the interview?
Here's a quote from the core interview:

In the latest letter from the producer, there's something marked as Instanced PvE content (Dungeon/raids). A lot of players are veterans of Final Fantasy XI so immediately thought of content like Dynamis, Limbus or Assault - Can you go into detail on what type of content we can look forward to in this regard?

It would be tough to say which it will be closer to, but if you had to say one, it will probably be similar to dungeons in other MMOs. But right now because we're working on the changes to the battle system at the same time, we're going to make something that can follow the progression--the evolution--of the battle system. Those instances will change over time as well.

Because a lot of this stuff is going to be high-level, end content, we want to make sure that the battles all have situations where you have to plan out the battle, have the tactics to defeat it--not only defeat it, but pop it as well. It's something that will be the high end, the hardcore content.

They're working on both. He's just mentioning the newest stuff.
