What does "battle area" mean in terms of developer language

[Pixela]

To me, this means a simple BCNM area.

However is that what the developers mean it as?

With the curation of new content like Voracious Resurgence, are there any plans on implementing new zones?

To me this meant a simple area such as Ambuscade or similar.

However, they have used this term in the past and applied it to Abyssea areas.

Final Fantasy XI:
Battle Area Add-on Part II
Scars of Abyssea

If so, then Reisenjima is as much a battle area as Abyssea. They are identical in terms of the kind of zone and how it is played.

Anyone have any examples of them using this term in a way that would give an idea what they mean here or can a community rep ask them what they mean? Cause there was a lot of talk about an area called Valhalla and it would be cool if that is what is coming and it's a proper big area.
