Honestly, aside from the Gil/Sprit Binding grind for Materia, the Novus portion of the Relic train doesn't seem that bad.
Granted, I don't yet know how much Alexandrite is needed to complete the Novus, and that could easily change how quickly or enjoyable the grind is. Also, yes, Materia affixing can theoretically fail here, but we don't know what the chances of that will be, so. *shrug*
All that aside though, you'll get one Alexandrite a day for doing an Expert Roulette, and you can do those in full parties of four now. You can get another one whenever you gather 800 Myth, and just gathering casually I can probably get one of those every few days, or I can Fate Grind Alexandrites, though of course I don't yet know the drop-rate.
Still, all in all this really doesn't look bad.
Anyhow, I have a question, as I really need to make a decision here. Basically, I'm torn whether I should spec out determination, accuracy, parry, or crit, for my Novus.
The standard Tank configuration of course, all but demands parry and accuracy. However there are some knowledgeable folks around that insist that DPS is king in this game. In the meantime, I'm pretty much constantly struggling with accuracy, but, if I luck out with drops and get the High Allagan Fending pants, it shouldn't really be an issue anymore. (Plus, ACC Materia is some of the most expensive crap out there.)
Basically, I think I'm hearing too many conflicting opinions on this, and I have no idea whose advice to take.
