Live Letter Digest request for clarification

[St0rmchild]

A few things stood out that I really would want an official clarification on:

Q: For the new jobs, will there be new weapons and gear added from existing content such as primal fights, raids, and Allagan tomestone equipment?
A: Allagan tomestones of esoterics, lore, and scripture gear will also include gear for the new jobs. These previous tomestone exchangeable gear will be available via poetics.

1) So a lot of old gear goes to the poetics exchange - that much I got.
2) Exactly which gear goes to poetics exchange: Lore/Scripture I get, that's per-role gear and currently available, but Esoterics is currently on Centurio Seals exchange. Does that go to Poetics as well then ?
3) This infers that there will be esoterics gear (AF2) for Samurai and Red Mage, is this correct ?

Q: In Patch 4.0 we expect equipment item levels to skyrocket all at once, but will there be higher grades of materia introduced?
A: Yes. The name is tentatively known as High Materia V and we plan on making them easily obtainable. As they are quite powerful, we plan on restricting advanced materia melding to one time only.

exactly how is "One time only" meant ?

a) You can only put one of them in Advanced melding
b) You can put as many in Advanced as you want, but you only get one attempt
c) You can put as many in Advanced as you want, but you have to do it in one go
d) all of the above is wrong and they're exempted from advanced melding

Probably stupid questions, but this just stuck out to me as a bit unclear, sooo. ...
