Gave Heritage another listen (7th), and it's weird, it's done what Watershed has done, where it sounds like any old normal Opeth album.
When Watershed came out, i thought the whole sound just didn't sound like them (especially the guitar tone, it was less forest-y and more clean/clinical). Heritage felt weird because of the 70s feel. But now it's just.. normal Opeth.
So Heritage is pretty awesome.
