I have not had a chance to verify this, but my question is do the same BO skills on two of the same type of officer share a timer? For example, a Lt. tactical officer and a Ensign Tactical officer both have High Yield 1. I assume that I use one then both will share the same timer? Or, does the global timer comes into play at this point (20 seconds?) and I could actually use the second officer's High Yield before the cool down expires on the first officer's?
