That's just it.

Throughout the life span of FFXIV, players talk about not having enough bag space. What they are really saying is less that they don't have enough bag space, and more that they have issues with inventory management. They can do it, but it's not fun to do it. You spend too much time in FFXIV managing inventory, and the causes for the frequency of inventory management are bad design. Bad pity prizes are examples of things that contribute to it. To get confetti items is worse than getting nothing, because now you have the burden of having to get rid of it. I rather it be like 1 gil, because then at least I don't need throw it out later.

The worst culprit is Eureka Anemos. I rather get 10% as many lockboxes if more of them had items of value than hundreds of lockboxes with confetti or items that have no market value because you made the drop rates so high they are worthless. They just don't understand good reward systems from a psychological or user experience standpoint.
