Depends on how non-hardcore we're talking about.

There're 4 months between the two batches of T4 releases iirc and assuming taco doesn't change anything. If you want to unlock Yori as soon as she's out plus one more, that's 1000 pages in 4 months = 250 pages per month = 8.33 pages-ish per day. Not sure what the drop rate for Och is for non-MVP, but 8 pages sound leechable to me. If you're diligent in doing your daily standard/expert/ultimte raids, you should also have plenty of raid medals left over after getting all the tickets/eyes and what not to buy more pages and cut that down to like 7 pages-ish per day.
