The idea with CoF is that you should be using it to pump out as many BCs as possible. The moment you need to delay this for a particular phase or adds or a burst window then its value declines pretty quickly.
Arms doesn't have the same benefit from CoF as it can be harder to line up appropriate BC windows with your other abilities.
From a quick look and some napkin math, I think the fact your CoF is 865 will mean that basically, any ToS trinket will beat it out since the strength loss is pretty high for either spec.
For Arms, I suspect you will find that the Vial will wind out even if you had an 880 CoF. Whereas for fury, the 880 CoF would win over the vial.
