Glad someone already posted some numbers on this
My favourite part this stuff TBH.
So Enmity VS STR (or MND) for PLD is:
1 ENM ='s 0.1% of Damage
1 STR ='s 0.8 extra Damage (up to probably 340 STR, similar to DD classes other than BRD)(also depending on weapon)
MND ='s 0.7 extra Damage (up to probably 310 MND, similar to other secondary stats)
So basically, the only time ENM>STR or MND is Either on Provoke/Flash/Rampart where damage is not included.
The only time 1 ENM ='s 1 STR or 1 MND is around a 700-800 Damage hit.
With a Quick calculation then, with a STR/MND build (bonus stats being divided into STR and MND as well) up to cap,
you can increase your WS Damage output by 50% on PLD, thus increasing enmity by 50% on average.
(Flat Blade Combo can be up to 400%)
Going with strictly ENM, between 300-400, that's an increase of 30-40% of low damage output.
Roughly 20% overall
So STR + MND ='s more damage and more Enmity Generation
It'd be dabateable if an Enmity Belt for PLD is even worth it over Double HP.
