Q56: Will the extreme primal battles be part of the main story and/or be tied with the relic quest?

A56: Yes.

This telling me that we can +2 our Relic by continue our Story and defeat he Extreme version of the Primal after the Hard Mode? I sure hope so because this can content for Hardcore players who even beat coil and get all their Allagan or AF2 already. If not there really no point beating it for bragging right and story if you already have Relic +1 Weapon.
