Blue Mage In Voidwatch

I've recently been trying out BLU in Voidwatch and I'm curious as to how other BLU's go about doing it. The obvious and most important role is to proc with our spells, not totally uncommon for the proc to be blue magic as I've proc'd high vurn multiple times on BLU.

After it's proc'd I usually run in and CDC with temp items up. Afterwards for damage I'd normally regurgitation for 400~600 dmg with ascetics up consistently. I've done a Dark Orb for 700 dmg w/o ascetics up in regular nuking gear and Thunderbolt for 500~700 w/o Jupiter staff on (forgot to take out satchel). Seems magical dmg is pretty nice, this is vs Kaggen btw. I tried out /thf, was able to do 700~2k heavy strikes.

What sub job choices do people prefer? MP was never an issue with temps/refresh. If people aren't /thf I don't really think physical spells will put out much unless under CA/efflux with QC perhaps.

One of the biggest annoyances was just sitting there during spell swap wait, felt kinda useless so I think a more supportive sub could work here for cures or -na's/erase/haste. I had been also looking at -% weakness weapons such as -15% DEF, -15% MDEF, -15% MATK etc. If they can land with any consistency vs real targets like the tier3's, then they will be extremely useful during the wait from switching spells. I took my -10% DEF sword out during Kaggen and hit him a few times (mainly for 0 dmg) and wasn't able to proc it lol, I'm not sure if the higher levels gain potency in the proc % or if there was already a def down in effect that was higher.

Some spells I'd normally set are White wind for a good ~1k aoe heal, not too important if you have a dedicated healer per party. Winds of promy, very useful, and the normal ones such as haste/refresh. Do people find it useful to select a group of spells that you will always be swapping out of? I think it would be more beneficial to plan ahead than to just randomly dump out spells to try and cram the proc ones in once you find the element.

As far as atamcites, this is the combo I use:

Atmacite of Destruction
-MP+50 "Magic Atk. Bonus"+10 Enhances "Fast Cast" effect +2
+
Atmacite of Coercion
-STR+4 AGI+4 Accuracy+5 "Regain"+2
MATK for our nukes and fast cast for spell usage, regain for CA and proc if its sword/club.

Few others looked decent like the voidwrought one and refresh sphere one but I think these two would be most beneficial (coercion+destruction).

Food choices, I normally go between Red curry bun or Sole sushi. Don't see a huge benefit from cream puffs even if you're relying mainly on magical dmg, you should still be able to run in and ws even if its vorpal during stagger.
