Correction according to my experience with healers:
Rank1
Take Heal, it is a must.
Drop Deprotection Zone, it sucks.
Rank2
Ressurection lvl 2 is enough unless you are doing pvp (arena) but you won’t take a paladin to arena, so you can reduce it too.
Monstrance lvl 1 will be nice for dex builds (no more than 1).
Rank3
Sacrament is a must, no discussion about it.
Revive it is a party skill, never a solo. Now, lvl 3 is more than enough, lvl 5 ok but you can use those points in your buffs.
No Mass Heal? Why?
Rank 4 - 5
I am gonna be honest, I am not fan of this class, I think it is underpower, pretty useless and their animations are awful. In the other hand one of the best costume in game. The only valuable skill is Resist Elements.
Rank 6
Stone Skin? Are you building a SPR paladin? I won’t take it. Again, Sacrament is a must.
Rank 7
Ok, why are you not taking barrier? It is the only good reason to be Paladin3.
At this point I need to ask you, what do you want to play? Some kind of buffer/debuffer, no healer, no dps? It is a serious question, I really enjoy building healers and wizards so I can advice you a bit but I am not sure what is your intention with this build.
