key Item Inventory - are 3 pages really necessary?

[Iscah]

It's partly an effect of the page-based layout of the inventory, and the slots don't really exist in the same way real inventory does, but I do suspect you could fill it up with a mix of effort and inventory creep.

You have permanent or semi-permanent things like the Wondrous Tails book and four hunt bills per expansion (two for ARR), and can still have the old aether compass taking up a slot even though it doesn't work. That's at least 20 items already, and the number will go up in later expansions.

You can have 30 quests active, which at least hypothetically could each have a set of three items to collect and hand to an NPC. That could be 90 slots taken.

That's 110 total items, and three pages is 105 slots.

Edit to add: due to the page format, you don't even need to fill three pages to need three pages. You just need to overflow the second page, so 71 items.
