Not sure if this is intended but, in two paladin parties, a Justicar who is tanking can't regenerate divinity while blocking if they are under the effect of a Divine Barrier provided as part of the Oathkeeper's heals from Divine Touch, Divine Shelter and via Lay on Hands feat Intervening Light. The barriers provided take the damage first before hits are calculated against blocks.
