I dont have Lance of Mitra healing cause of the sick mana cost. Also 5 points in Holy Accession increases mana control. Splash not the best, agree on that, but holy vengeance is meh too imo. All in all it doesn't make much difference these points. If you got 9-10k mana, I guess you can feat Lance of Mitra and only one point in Holy Accession but I leave them out as I said because of mana management.
