Please understand that once fully upgraded, a base is generally considered to be more beneficial than silver boxes.
We understand however that currently getting to that point can be grindy. We're looking into future improvements to potentially make it feel more rewarding faster.
If you would however still like to disable your base, you can do so safely, once. After one initial base removal, we reserve the right to reject future ones. Having your base removed will not return any gold spent on the base, so please be mindful of that.
You can currently request for us to disable your base via this form. We will add the option to disable it yourself as much as you want via another method in the future.
