Paladin gauge is fine. Using it to block AOEs or random autos gives you 2/3 of a Holy Spirit. If you combine that with other random MP sources you can easily replace 3 non-Fight or Flight GCDs with Holy Spirits in some fights and increase your DPS while still making it in time for the Requiescat window. You can also use it to fill up MP on bosses that force you out of Riot Blade range. It also lets you slip in Rage of Halone when you need enmity. Alternatively, you can use it defensively for blocking tank busters or Intervention. Probably the only thing I'd change would be to add a little bit more information to it - crackling lightning around it while you're above 80% MP or something.
