I was really looking forward to stacking warp scrolls. An enchanted item is a completely different thing. We have plenty. Sure it saves us some space as we probably only need to have a single extra one since 10 minutes is likely to be fine for most things but my biggest issue is that enchanted items must be equipped and then you have to wait for their timer before use. A stack of 12 warp scrolls would be great. Done with what you're doing? Hit a macro, you're already on your way.
As far as requests to make you able to buy more than one warp scroll? Really? They would make a change like this and continue to make you purchase a single at a time? What would be the purpose of this? They aren't going to get any extra sub money from making me buy one at a time and honestly, a fix for this wouldn't be that hard. Just do an abyssea stone like method of "Fill me up!".
On this note, could we do away with this archaic pop up text menu purchasing of items? The game has a perfectly viable system already. NPC purchase screen, just make this particular screen cost CP instead of gil. If you want, you can put a big warning across the top or just mark each cost with a colored "CP" or whatever currency this particular purchase will cost. There are several benefits. One being that you'll be able to look at an item without having an item confirmation menu pop up for each individual item. Then you can pick the exact number you want to buy and buy them quickly and immediately without having to buy odd or stupid combinations of numbers to get what you want. Oh? you want 10? Well you're gunna have to buy 3 sets of 3 and then a single!
A stupid simple fix for a metric ton of menu issues all in a convenient already developed package.
