PDT vs Defense

[Sechs]

Anybody ever bothered to evaluate this difference?
Maybe I'm being absolutely stupid but I noticed a very large difference between some of my sets.

For instance Arhat+1 (head/body) gives me 15%PDT and 59DEF, in just two slots.
Taking as comparison Otronif for the same spots, and considering very low augments of 2%PDT each I'd be left with 4% PDT and 190DEF, but I would also gain +36VIT, +64HP, +61Eva, +3Counter and +11Haste.

So, would the added benefit compensate for the loss in PDT in those two slots, or is the difference too big?
(yes, I'm trying to clean up my inventory )

If you want to browse through the last few pages in the MNK thread on FFXIAH, Motenten put up some math on it. Essentially, Arhat's is not longer worth it with Skirmish II gear, but the body is better than anything but that. Head was outclassed even by Whirlpool.

I'll go read it immediately, but even if Arhat still wins, as long as the difference is reasonably small, I think I'll favour Otronif for the simple fact of: 1) +2 inventory, 2) +1 job that can use it
Hope you don't need perfect 4%PDT augments because I don't think I have the will/time/money to sink that much gil into gear that might get outclassed in a couple of weeks.
Thanks for the tip meanwhile!

Ok so THIS was the post, altough I suggest reading the following ones because in the first one Motenten forgot a few variables, the following posts are more accurate.
To sum it up in two aspects:
1) The more base def you have, the more additional def you need to compensate for the same X% PDT loss.
2) The more PDT you already have, the more additional def you need to compensate for the same X% PDT loss.

Motenten's post was made before Otronif gear was released and from the stats he posted I think also before the Delve gear revision which added lots of stats.
For a big tl;dr, even with ~25% PDT and >650 DEF to start with, majority of high ilevel SoA stuff beat old pre-SoA PDT options.
Of course it gets even better when you add Otronif to the equation, since you can easily put at least 2% PDT there.
Only "exception" is Arhat's Gi +1, beating 9% requires more work, but Otronif Body can do that and probably more stuff too.

So yeah, it seems I have some cleanup to do in my inventory xD

I use a simple math equation to determine physical damage mitigation for gearsets now.

(100-(PDT+DT))/Defense

The lower the number, the better. It assumes that monster pdif is linear, but other than that, it's quite accurate. Just make sure to include the effects of Protect V when comparing gearsets geared towards endgame enemies.

If you really want you can just plug stuff into pdif formulas for more accurate answers. Not that much math really if just comparing 2 peices. Just remember relevant buffs and that dt hss increasing gains while def has decreasing and both have caps of sorts

[Fwahm]

We don't have formulas for monster pdif, do we? Not to mention it'd be impractical to change your DT or Hybrid sets based on exactly how much attack your current foe has.

I just opt to the whatever won't make me die while having the most DPS route.

Not sure... I think someone figured then out via doing pets awhile back. And mote did some math. Wasn't really suggesting sets that situational but you could theoretically get one more oriented towards the content you are using that job for. Though I don't expect it to make much diff in gear selection outside of hitting ratio caps.

Plus I don't really understand your equation. It looks like you are basically subtracting pdt from 100% but then dividing the pdt by def doesn't make sense if that's what you were doing

[Fwahm]

A mob's attack is divided by your defense to get their ratio, so how much damage they do is (roughly, and assuming your defense is below their attack) proportional to 1/your defense.

After that, the damage is multiplied by how much damage you take, or (100-(your PDT+DT))%.

Thus, the damage a mob does is proportional to 100-(PDT+DT) divided by your defense, or (100-(PDT+DT))/Defense (there was a missing set of parenthesis in my original equation, which I now fixed; that might have been what confused you).

[dasva]

Yeah that lack of parathesis did change things alot. I'll accept that pdif and therefore damage is somewhat proportional to ratio ( at least in soa until I can dig up whatever mob pdif data I can find lol) and that with a set assumed mob attack that means proportional to 1/def.Part of what was throwing me off for some reason was thinking it was a straight percentage dmg reduction from some absolute like 0 pdt 1 def or something not a proportion comparing different close sets. I blame too much sun. Though at some point some heed should probably be paid to pdif caps/floors from some abritary but plausible att amounts. At least during crazy extremes like super high vs trash 75 content or low def on boss delve
