I'd recommend announcing your superbol before you use it, where possible.
For example, even though I'm a healer main, I often end up tanking my experts as GNB, and because I like to pull large, that requires CD management. I'll typically plan on opening certain pulls with bol, and I'll tell my healers before I even sprint that I"m going to do that...because in their shoes, I'd love to get the same treatment.
...I've also had nothing but praise for doing so.
