PLD Novus: Parry or DET?

[Izsha]

Money is not the crux if the issue. Acc, crit, det, and never touch tier iv is what you do if money's a problem. Not do parry. That's the point. Parry should never really be on the table and being broke doesn't change that.

Parry:
*has very little defensive effect. 11 points roughly 1% increased chance to block 25ish% damage. That means 11 parry is about 0.25% damage reduction. 110 frigging parry is about 2.5% damage reduction. Oh and did I mention it does zero for magic? And zero of the m9nsters isn't hitting you? 110 crit is about a 5% increase in dps and ALWAYS works. Oh did I mention that putting on a shield waters down that 0.25% even more (depending on block rate). Parry is bad on war. It's HORRENDOUS on pld because shields are litterally stealing parries value.

Parry is really, really, terrible. If you can't afford tier 4 then don't waste what little gil you do have on a terrible stat.

Just to drive this point home!

T13, the only meaningful attack you can parry is Flatten, which you will likely block more than you parry anyway.
Ack Morn is Magic, as well as the 3-1 Flare Breaths after the Phase 1 and 2 Flattens.

So, with Flatten itself aside, you can only parry Bahamut's auto attacks. 1500~ Unmitigated on a Paladin in Shield Oath.
Bahamut auto attacks you roughly every 4 seconds for 9 Minutes and 45 seconds of the fight. (estimating for while he is using flatten, Flares, and Earth Shaker, Flare Stars..)
That adds up to around 150 Auto attacks in total. (if we assume he will reach the enrage flare.)
So his auto attacks will hit you for 225,000 Damage. (Unmitigated)
5625 is Baseline parried. We are expected to parry at base 10% of those attacks for roughly 2.5% of ALL the damage to be mitigated.
The best possible Parry set adds 217 more parry than the best possible DPS Fending set. Which is an additional 2.82% damage expected to be mitigated.
Which adds up to an additional 6345 damage to be mitigated over the 9 minutes and 45 seconds of Bahamut attacking you.
The best DPS Set gives you 138 Crit Rating and 71 Determination more than the Parry set.
So is it worth it? Would you trade 8.8% Crit chance and 71 Determination(21 Strength worth) for 6345 damage mitigated over nearly 10 minutes? (That's 10 DPS FYI)
