Yeah I worked on that recently. When the patch came out I sunk majority of my points into DEX and maybe a third into PIE so it's not very high overall. To counter that I picked up another rainmaker's tunic, got a +16 Piety materia and had it melded to that. Additionally I got a pair of felt kecks, added +10 Piety to that giving me +14 Piety with that piece of armor alone. Adding in 2 Piety rings I've raised my total to 271 Piety with 298 Dexterity in the trade-off. I'm much more satisfied with this setup though some people I know are insisting it's best to go all DEX/PIE and not waste anything in Strength at all and to focus more on Dexterity than Piety. I haven't had a real chance yet to test out the armor changes I've made since then yet I've noticed Bloodletter does stick more often during Ifrit fights than it did before.
