Well according to the jp dev posts seems blockrate for pld might blow hard so aegis might basically not block and testing with the +188 parrying has shown awesome rates for pld who has horrible parrying. Everyone can cap pdt easy so run might end up being able to mitigate physical dmg better than aegis pld if block rate tanks. So then looking at magic... even with merits and capped mdt aegis will take half as much from all magic as run does from 1 type.... but with a decent resist rate will actually average decently lower. And that's with vallation merits seeming to be bugged from the testing I did and being to low. So if blockrate on shields starts taking a dip pld might find itself out of a job
