Sorry for the late reply. As is, your build's already very functional.
Otherwise, regarding all of the skills you mentioned,
- Gloria is decent for the low skillpoint cost, especially if you do raids, where you're likely to be using Heal more often. But you can live without leveling this.
- Archangel is still good for healing since it increases your matk, and your heals are based on your matk. It's not an immediate save-your-life skill like Coluceo, Assumptio, or Sanctuary, but it's good for helping bring bad situations back under control.
- Sanctuary, I only see a purpose in leveling it if you want to be able to cancel the skill sooner. So for the most part, Lv.1 is still fine.
- Suffragium directly adds to your Haste Rate, which only affects your casting speed (specifically the yellow casting bar; animation is not affected). So yeah, it effectively shaves off 0.1 seconds from Heal and Holy Light. In the future, I think it could be fun to use with high-tier crafted gear, but is it worth sacrificing Vigor for that? I think that'd be situational.
If you're not interested in any of those, then consider spending those points to go hybrid.
Well, there are a few things I disagree on:
It*s basically chance for -1sec for Heal. You can't cast the next Heal directly thereafter; you have a delay of ca.1sec. Therefore Gloria "halves" the overall casting time, what also equals 15% more damage.
Well, a 15% to do a crit. hit (double damage) equals 15% more overall healing, but the use is limited to 1 spell (2 if you're going hybrid). So it might seem a bit more powerful than Sacrament (5 skill points for 10% more healing). However, I've noticed that in harder dungeons it is quite irrelevant how much more you heal on a regular basis. Most likely, those AoEs or certain other critical situations might cause some losses until the party isn't 'stable' anymore to kill that boss before the time runs out (the rage counter triggers)
So although I've leveled Glora, I wouldn't recommend it for a Full Support Priest.
Also keep in mind that Haste reduces the casting speed as well. Therefore, the overall benefit of Gloria gets weaker and weaker the higher your haste rate gets.
The bad thing here is that it's a long way down to level Archangel. You have to level some useless skills to get there, so it's rather a "spend 9 skill points for temporary +25% damage". The average damage increase for this spell is 25% * 30/90 = 8.3%. Put both comments together and you have: 9 skill points for 8.3% damage increase.
Well, I am a bit unfair here, because as I said above, the average healing ability isn't that important later on. Therefore, Archangel can give you a plannable, more powerful bonus in crucial situations. Is it worth it? - I can't really tell. Most people seem to be fine with a lvl 1 sanctuary (lvl 5 is a 47.5% healing increase in comparison to lvl 1), so if you get satisfied with a 25% bonus might be questionable as well.
Won't comment this here again, but I have it at lvl 5 and would always level it up to 4-5 again.
Yes, I heard this tale soo often right now that it only affects the casting bar, but I honestly doubt this is true. Otherwise, Assassins shouldn't use haste at all (how many casting bars do they have???). So I think this fastens animation and "recast delay" as well, granting a 10% overall action speed and it scales with other haste boni (gear)
I have it at lvl 5, but would I do this again? Probably not.... for the same reasons I wouldn't level Gloria or Sacrament. Right now, I would even prefer to level Coloseo Heal instead. In non-crucial situations, people ought to use pots if I can't keep up to have everyone at full hp. However, if the tank received a critical hit and his HP is suddenly dropping below 25% HP, you better wish for some instantaneous and powerful heal.
What you missed out is:
Well, although it's unfair that a Priest gets a skill that is basically a Spinel replacement with such an aweful cooldown (blame them for making money from dying characters >_>), but I really, really wish I had leveled this. A level 3 resurrection means that you can use it in PvE H while engaging Gearbats AND use it again during a Giant Driller fight (or later). Otherwise, you might not want to use it at all to keep it ready when facing Rosario (Einherjar).
