I can understand that we can't switch items from different classes, but when it's the same, it feels very frustating. 

With all the new season system (giving opportunities to get easier XP, skill points, inventory slots), or any other reasons, we could want to (re)create twice the same class.
For exemple I have a new Musa, but I can't give him my pearls items that I bought for my first one that I don't want to play anymore.

I really feel that this character lock is unfair, and should be bound to family instead.

Hope one day it will be changed.

This is purposely done this way, in order to force you to buy new ones if you want to use it on multiple chars.

I don't think they will change it, and neither think they should. This isn't P2W, and since it's basically a F2P game, they gotta make moeny somehow.

I wouldn't expect them to change it either, but since most players never create multiple characters with the same class, such a change likely wouldn't have much impact on PA's bottom line, and it would certainly be more customer-friendly for them to make such a change.

I agree. Perhaps, it would be nice for users but I am not sure it is worth the resources spent for the developers since buying new ones has an obvious benefit.

I am not one to have more than one class on any MMO.  I did that once, but it was only because the game charged cash money to switch builds.  I no longer play that game.  I am aware that many armors you aquire within the game are universal (Loure's Lost Armor set) for all classes, they could sell a premium outfit that wouldn't be bound to character and yet fit all the classes.  Then they could add a heavier price tag to that set, just to be fair.   I wouldn't buy it, but I imagine there are those who would.
