Wait, when do they start adding the SSR grails to events?

I agree that one should never spend draconic eyes to exchange for them, but that's more to do with the fact that their effect can be replicated in ways that don't take a 10 week resource to do. The very idea of acquiring an SSR grail through eyes is so bad/unnecessary, that the wiki page explaining the skill level up system doesn't even mention how many points an SSR grail is worth.
