/ tldr at the bottom

So I've noticed something about these new cave things. I have been exploring a lot since the implementation of them, and I myself have only gotten one item to build my caves with. I like the idea of caves, but they just seem a little useless if you aren't even able to create them easily. So, I'm asking that the drop rate for cave building items be raised so that instead of it being a rare chance (as it apparently is), it's much more common. Why force us to deal with this if it's not even going to be easy?

Also! As a bit of an afterthought, why is the additional SB price so high? I get that the caves are a privilege but it seems a bit... I don't know, redundant.

I'm not asking that the price and whatnot just be changed completely to GB, as I myself am a user that isn't able to get GB and I don't want yet another thing unavailable to me because of that, I'm simply suggesting that the drop rate be raised and the SB price be lowered.

:edit: Another suggestion is to make building either by getting the materials OR the SB price. Not both, because of the aforementioned problems.

tldr; higher drop rate, lower SB price.
