Question about Storage Boxes

Why do I have to pay for a storage box with each of my characters if I must share the space between?
Edit: share the space in the storage box between all my characters

What?

yes you have to pay on every character

Lets try this again, as I think I've expressed myself poorly.

I don’t think it fair that, when I pay full price for a storage box it's not completely empty. In my case it was half full of stuff that my other character put in storage, who BTW, also paid full price.

You're paying for Access to the box for each character. You're not buying a brand new box for each.

this way u can transfer stuff too

It's 50g no? I can make that in 2 mins, stop complaining

I was actually extremely surprised that I had to pay the 50g when I tried to access my storage box on a new character. I'm not saying it's a big deal, it just doesn't make much sense. If it's linked to an account, logically, you should only pay once. Just my opinion.
