It already *is* "strength based*. The enmity generated by Flash is dependent upon your attack power which is directly impacted by your Strength (in fact, it's the primary contributor).
The entire point of Riot Blade is to regenerate MP. It's not simply a "spam more Flash" combo. It's a combo that's there to allow you to make up for the terrible passive mp regen that PLD has given that more than just Flash costs MP (both stances, Flash, Stoneskin). Extra parry would be increasing mitigation where none is needed and giving it more MP support capabilities isn't going to make it any more attractive for purposes other than Flash spam: Flash is a spell so that's basically what your cost redux proc would apply to and, even with 100% additional potency, Cure is still laughable on a PLD (and doesn't scale with gear, either, since PLDs don't stack MND so the proc would become pointless ridiculously quickly).6. Give Riot Blade another "additional effect" (maybe something like increased parry +10% for 6s, or 20% chance next magical cast cost 2/3 MP or something just to encourage its use except to generate MP to spam flash. Or 20% next cure spell is 100% more potent.)
This opens up a whole can of worms that requires reworking the enmity math on pretty much everything PLD gets. If you want to *require* players weave in attacks rather than spamming RoH, you've basically got to hamstring the enmity generated by RoH while simultaneously beefing the living shit out of the other attacks, both of which are exceptionally problematic. Flash is an AoE and, as such, forcing it to be spammed for ST purposes is basically preventing PLD from being able to effectively tank any time they have to tank in close proximity to anything else that they shouldn't be tanking (re: any time an add spawns nearby that they're not supposed to be picking up, which happens plenty often). Shield Swipe is a high conditional proc which means that its contributions are unreliable and actually end up being nonexistent on some fights (any fight against a pure magic opponent completely precludes its use; ex. if you're on Levi's head, the only way for you to get Shield Swipe to proc is to get attacked by the adds).7. Lower the enmity generated by Rage of Halone, requiring players to incorporate Flash and shield swipe into a more complex rotation.
Weakening RoH is not the solution to making PLD more interesting to play. If you want to make it more interesting to play, you should look into buffing the other options so that the best thing for them to do 99% of the time is just spam RoH. Giving Shield Swipe a 3-4x enmity modifier so that it isn't a net loss to enmity generation would actually go pretty far in making the PLD rotation more interesting since you're incorporating a time dependent proc-activated ability that increases damage and efficiency without having said incorporation end up reducing your enmity generation significantly. I main as WAR and found PLD to be singularly mind numbing to play up until I decided to start incorporating Shield Swipe because it actually requires you pay attention to some degree, and, to use it optimally, requires a modest degree of forethought.
I seriously have to wonder why you seem to think that the devs have a problem with PLD such that they're making it "more useless in certain fights". Ifrit HM has been a joke for the longest time and had been a joke long before the devs tweaked the DR on stun. If anything, the change to stun DR actually made PLD more interesting on Ifrit HM because they were given a reason to actually *do* something other than sit there and wait for Eruption so that they could use Shield Bash.10. Dont readjust content such as stunning Ifrit or flashing Titans mountain buster making Paladin even more useless in certain fights than it already is.
I'm quite curious as to which fights a PLD is "useless" for. If anything, the increased utility a PLD provides (silence, HG, stunlocking) actually means that a PLD is basically required in way more situations than a WAR is (in fact, I can't think of any situations/strats where a WAR is required but can think of plenty where a PLD is). WAR is *optimal* in a number of situations when compared to a PLD, but that's nowhere near rendering PLD useless. The only possible way I can interpret "PLDs are more useless in certain fights" is that you're pissed that you're not basically *required* to have at least 1 PLD with you for every single piece of 8 man content in the game.
Woe be the PLD because double WAR is actually a *viable* composition that's still inferior to WAR/PLD. /sarcasm
The basic reason is that it's not really a problem so why bother fixing it? I've yet to meet anyone that thinks that GLD and PLD have insufficient enmity generation tools at any point except for those people that think that enmity should be a complete and utter joke at all times. Flash works just fine and ShO isn't even really needed until your late-40s. The only reason that anyone complains about not getting Shield Oath at 30 is because WARs get Defiance at 30 (and the reason that WARs get it at 30 is that *every single one* of their other job abilities depends upon it). If WARs got Defiance at 40, you can be damned sure no one would be complaining.But Coth wont stand for a simple swap in Shield Oath to make the job more enjoyable for what reason is beyond me, so we'll see how he reacts to this list i guess..
If you really want to provide a list of suggestions, try to make sure they're not either painfully obvious ones that have been suggested time and time again (Shield Swipe high enmity) or bad ideas that simply demonstrate how little you know about the game (Flash enmity tweaking; Flash animation tweaking, as if it would actually *do* anything, "don't readjust content").
