Personally, I don't have a clue how to dat mine, but others do and post their findings. If you read any other FFXI forum, you'll see dat mining's being published, notably after updates. SE has to be well aware of this. In any case, a youtube video was posted in October of last year that contained what appeared to be an animation for Tier III March, among other interesting things (this was back in the time of Meteor/Arise being announced, etc.)
Basically, I'm just annoyed that it took over a year to get any kind of response regarding an inquiry into this. And then to get a response saying that March III is being planned on implemented but...
It's terribly unspecific, just like they said with Massacre Elegy ages ago. As players that pay by the month for FFXI, we deserve to be given more precise dates and information on content that will eventually be produced for it.
