Moar stash space needed.

Common, Crete, 2017, why do i need to use mules or shady software to keep my stuff? What the point of this restriction?

I am not a dev, but some of the crafting recipes search into the stash for available components, maybe if it is too big, it slow down ?
At least it could be a reason.

What I would have liked is that some quest items or components used for crafting like scrap, dynamite, manticore eye… could be just a line in the UI like D3 did so it could could stack infinitely.It would free a lot of space.

In D3 you have a list of crafting material per char. You can not share or trade.
In GD you have a pool of crafting materials per account. You can share with all your characters and use it for trade.
