That was exactly my thought, too. I personally think 90 per day would be the ideal number (5 days to cap), but I expect it would be 75 to match the esoterics you get from an expert roulette. Even if it were 75, you could still cap in less than 6 days by doing a few of the easier turn-ins. Crafting 4 collectibles a week to cap sooner so you don't have to do the daily seems a lot better to me than crafting ~25 collectibles every week just to cap with no other options.
