Are Holy Spirit and Holy Circle Pointless...

... once you have Confiteor? I cannot see a purpose to either when that big sword stab is so much more potent (aside for the need for them in content between levels 68-79).

Confiteor is your finisher, as once you use it, the Requiescat buff ends

[ReiMakoto]

Confiteor cancels your requiscat immediatly upon using it, so in order to maximise your req windows you need to use 4 holy spells then confiteor, as that will bottom your mana and get the full effect of the req potency buffs

Ah, okay. Thanks.

Now, I barely play PLD so correct me if I'm wrong... but the potency buff of Req is only active while you have 80% MP or more anyway, so only your first two spells feel the effect.
So surely using just one Holy spell, then Confiteor, would be a DPS gain even with dropping Req, so long as you're not forced to move?

Holy Spirit: 350 +175
Holy Spirit: 350 +175
Holy Spirit: 350
Holy Spirit: 350
Confiteor: 800

vs.

Holy Spirit: 350 +175
Confiteor: 800 +400
Holy Spirit: 350
Holy Spirit: 350
Holy Spirit: 350

It's just those last 3 Holy's aren't instant anymore.

The buff only activates if you meet the MP requirements, but once it's up, it's up for the entire duration.

Requiescat checks you current MP when used. If you have 8k to 10k at the time of use, it gives you a 12 sec buff that increase Attack Magic and Healing Magic potency by 50%, makes spell cast times instant for the duration and allows Confiteor to be cast. The Buff doesn't care about your MP; only Requiescat (which grants the buff if you have enough MP) does.

Holy Spirit: 350 +175
Holy Spirit: 350 +175

The actual potencies for this burst are:

Holy Spirit: 350 +175
Holy Spirit: 350 +175
Holy Spirit: 350 +175
Holy Spirit: 350 +175
Confiteor: 800 +400

With all Holy Spirits being instant cast.

Tooltip needs clarifying then.

Tooltip needs clarifying then.

To quote Requiescat tool tip:
Deals unaspected damage with a potency of 150. Potency increases up to 550 as MP nears maximum.
Additional Effect: Increases attack magic and healing magic potency by 50% if current MP is at 80% or higher, and allows spells to be cast immediately
Duration: 12s

Surely the "Duration: 12s" and the "current MP" makes it pretty clear? You deal your 550 potency Requiescat at full mana then get the buff for 12 seconds.

It is clear if you know how to interpret FFXIV tooltips which, let's just be honest here, can be pretty damn cryptic at times.
It really wouldn't hurt to change the wording on that one so that it can't be misinterpreted. We've all seen PLDs doing instant confettis.
