It seems to me that the stumbling block (i.e. more scarce drops) for Epic Crafting are now Seals rather than Shards.
Is this WAI?

For the record: soloing, so I realize that I have much less of a chance seeing a drop than if I were in a party. Chains involved: Carnival, Defenders (BoB to TT), VoN, Red Fends. Difficulty: most EN, some EH- difficulty seems to have zero effect on drop rate though, again, I am soloing so we're not talking much of a difference from the drop rates I've seen postulated.
