Limit on storage compartment

Hello
I am not sure if I write this in the appropriate part of the forum, but if you do not, I apologize in advance.

 

Why there are no restrictions on the storage compartment on 22. If you can put only 22 towers?

 

 

 

And besides, the conquest matching system still sucks

Why should there be a limit?

The question here is…

Why would anyone want 30 arrow towers?
