looking for healing advice for a PVE Paladin

[Concillian]

Though, I have toyed with not taking divinty and taking 3% more crit and the movement speed in ret. My question is, What's going to be better? 3% crit or 5% more throughput?

This is something that is somewhat situational. Most likely the extra utility / regen offered by the 3% crit + runspeed will outweigh the better throughput of +5% healing.

You also have the alternative of +run speed and +3% healing. This would be the utility of run speed, more throughput than +3% crit, but less mana friendly due to illumination synergy with +crit.

I feel it's a personal call and there is no truly correct answer.
