I think more bank space should be added for those who are subscribers.
What would you do when the sub runs out? You’ll be forced to buy a sub again otherwise you’ll never be able to bank anything new again ?
Probably the same thing that happens in RS when you run out of members and you lose access to the additional space.
You can withdraw and deposit current stacks of items but you cannot add anything new.
So if you had a full bank with some coal, you could keep mining more or even smelt some.
But if you only had 1 r2h and withdrew it to use, you wouldn't be able to bank it again until you either cleared some space or resubbed.
+1 to more bank space. Totally fine with the idea of having to sub for it. Even extra space for double sub?
