My 2 cents,

Jamba Proc is generally broken (due to changes in combat log and not much love) and a work in progress, but it happens to work very well for Paladin art of war procs. When a paladin in your team gets an art of war proc, a progress bar is displayed on the master toon that counts down the time left for the proc. If the proc gets used or reprocs, the bar is updated appropriately (removed or time reset). It's a little intrusive but might help someone.
