Simple add-on to track whether you are on cooldown to apply roaring opportunist.
Shows the duration of Major Slayer gained
Two timers to track for the full group.
Known Issue: The timing can get slightly off while counting down, so sometimes applying RO immediately upon the buff falling off may not start the timer.
