To be fair, from what I gathered, only thing(s) we are missing compared to DMM'Aigis when it was at our position on timeline are beginning of Revivals (and Serial Codes, but they are entirely another can of worms, connected to the licensing, production and distribution of physical goods and deals with press and festival committees).
Everything else came later.

Besides, with Awakening, Demon Crystals are precious commodity to waste them on more useless bed-warmers like Gold Angel and such! XD
