I cannot say except equipment slots, most of the golds I use have full equipment. That is why I have to say a waste (for me). They still worth blooming, just not for me. "Me" is the keyword.
By all means, please bloom them. They deserve love as well, I just not going to be the one to give it until everyone of high need is done by me first.
