Making Destroyer's probes stop dropping health would make him far too difficult for people entering hardmode. I think his difficulty is fine as-is.

Golem I think is fine, though they could upgrade him properly by doing a single thing: make his fists go through platforms. That'd remove a significant benefit of the wood platform partition method of dealing with him.
