Ran into the Tree for more Parry skillups to test out this roll as a follow up to the last two posts I put in this thread.
Gonna note, that I'm quite sure this was absolutely not the "intention" the dev's had developed new Gallant's Roll. But, if you read my first response in this thread, I was absolutely ecstatic and giddy at proposed Phalanx. Here are some numbers.
TL;DR: 75COR still trying to parry skill up. Change to Def roll makes no difference because it was only sort of meant for high defense jobs.
Defense: (75COR/37RDM) fighting against Even Matched Korrigan.
Equips alone: 256
+10 [vs. Plantoids Evolith]. The +10 never shows up on actual defense value when engaged with mob type. Also using -28% PDT in gear.
With Protect IV: 311
With Salted Fish: 397
With Bonused 11 Gallant's Roll: 489
With Phalanx from support job RDM
Damage received on average of 25 hits with Bonused 11 Roll: 25.12
Damage received on average of 25 hits without Gallant's Roll: 28.00
Proposed damage received if original effect was implemented: 0 (28.00 - 30)
Will try /BLU for Cocoon which should boost DEF to roughly 730 and try again.
Update:
Tried 75COR/37BLU with use of Cocoon.
Got DEF near 700. Fought EM Korrigan. Took more damage than without subjob Phalanx. /sigh. Gonna disregard Gallant's Roll and stick with good 'ol Regen/Refresh rolls on COR/RDM.
