4.0 plans for crafting and market?

[craized]

But unlikely to happen, in my opinion. Instead I expect we will have more spaces in our backpacks, more spaces in each of our retainers, and hopefully more spaces in the FC chest.

Especially that latter-- my wife and I have three crafting characters each (we each have two 4-star omnicrafters--for the specializations-- and our third characters aren't there yet), and the FC chest is how we share materia, mats, and craftings between our characters. It's stuffed, even with us limiting each unique item to 99.

I'd say increasing stack size would be a smarter method of inventory management.

I'd say increasing stack size would be a smarter method of inventory management.

Why is it smarter? If you have 200 different stacks of mats to store and only 150 slots to store them in, increasing the number of items that each slot can store doesn't help.

And then there's the issue of what fraction of players would actually benefit. 999-item stacks probably only benefit a minority of very active crafters. But everyone I know has had to work around the limitations on how many unique items (e.g. glamour gear) can be stored in their inventories.

If you're talking software effort, don't trivialize the effort it takes to display 3 legible digits in all the spaces that currently only display two. Making each row of the company chest 10 slots, instead of 5, is simpler. Or better yet, make each page of the company chest identical to an inventory page (100 slots in four 5x5 blocks, or whatever it becomes in the expansion) for a total of 300 items instead of the current 150. That reuses all the existing code and graphics forplayer and retainer inventory.

You're welcome to your opinion of what's "smarter," but is there any logic to it?
But odds are whatever they are going to do is already decided.
