Question about using Nocturnal Sect?

[Reinha]

In Nocturnal Sect, Aspected Benefic has a potency of 250 and 130% of that as a shield on top. It's a total of 575 potency for 707 mp. Benefic II is 650 potency for 796 mp. Their mp efficiency is almost the same, Benefic II being slightly more efficient on top of being more powerful:

575/707 = 0.813
650/796 = 0.817

Basically the only reasons to use AB mid combat are preparing for massive spike damage (like Final Sting in dungeons or tank busters in raids) and instant cast healing during movement. Then again you have Lightspeed for casting instant heals and Stoneskin for a bigger shield...

Now let's have a look at AoE in Nocturnal Sect. Helios is 300 potency per target and Aspected Helios is 150 potency + 150 potency shield per target with a bigger mp cost. Uhhh... Clearly AH is completely useless, unless your group's lives are somehow dependent on that 150 potency shield.

On the other hand, Aspected Benefic is a whopping 1030 potency and Aspected Helios is 600 potency per target in Diurnal Sect. You have 5% attack speed instead of 5% spell power, which doesn't make a big difference in your average healing output but makes you spend mp ~5% faster in Diurnal. However, having powerful Aspected spells more than makes up for the faster mp usage and also allows more burst healing.

By being in Nocturnal Sect you give up 2 very powerful healing spells in exchange for having two spells less efficient than Benefic II and Helios... And this isn't even counting in the AST buffs that only benefit you in Diurnal. Whether you are playing with a WHM, a SCH or solo healing, Nocturnal is crap (except for out of combat shielding). It's only mildly useful when paired with another AST because the regen effects don't stack.
