Invenory Expandation (backpacks)

This is my first suggestion on this forum of Wynncraft, but I hope you like though.

I play Wynncraft since approximately 4 years and it was and still is fun through new suggestions of players, that makes the game every time a bit better. And now I want to contribute my idea:

The longer you play the more Items you get and you don't have enough space for them. Since an update the bank can be expanded, but if you are on a farming tour or loot run, you're not always able to go to a bank. The players Inventory is often rapidly full and you don't know what Item you should drop. But the problem can be solved I think.

Backpacks could enlarge the Inventory. You could hold them as an Item and by rightclicking it, it opens a window where you can store your Items.
These Backpacks could be obtained by making a quest where you get this Item. And as with the horses(which can be bred) you can make them bigger at a shop where you can buy them.
But I would do it that everyone can have just one backpack at a time(doesn't matter which size), because this would be very overpowered if you have your hole Inventory full of backpacks. This problem can be solved by making them untradeable and you can buy them in a store for exchange of your old backpack(but only if it's empty).
Maybe there's a way like with the bank(that you can buy new space), that you don't need to make a store for upgrading the backpacks.

For the quest: This could be a new place(maybe a Post office) where you need to travel around the map and be a Deliverer for letters and backages. For your diligent work you obtain the backpack from the Post office employee, who hired you. The quest could be started in Nemract or Llevigar, because these towns are the gates to the different Wynn regions.

 

Add a poll.

Also, the backpack idea is pretty interesting, but the quest is not that good of an idea. What could instead happen is you can purchase one in Detlas, and then upgrade it at other major cities for a hefty fee(maybe starts at 5 slots at a level 10 pack, and each 10 levels gain a slot).
