You cannot improve on 969696 for single target, so that's not it. Try Touched by the Light. You're rocking 0 spell power, I have 1020. Actually, go beyond that. Try looking up prot paladin builds that go 0/53/18 and do not have divinity, 2 points in SA, or 5 points in conviction. Then make yours the same. Then change all your glyphs. I recommend divine plea, SoV, and judgement (unless you only tank trash or 5 mans, then keep the HoTR).
