Your opinion on best hyper stat for Hayato?

Point for point, %critdmg stats give the lowest benefit of the lot. 3 main reasons:

1) you need 100%cr for maximum efficacy of %critdmg.
2) %maxcritdmg and %mincritdmg each gives only half the contribution, because %avgcritdmg is averaged between %maxcritdmg and %mincritdmg.
3) you start with a base critical damage multiplier of 1.5, which already sets it well into the diminishing returns regime (everything else except IAS starts from 1 i.e. 100%).

So, in my case as a Hayato, I will go for %PDR first?
"Lv10 %boss/total dmg first > %ignore def > %crit dmg%ignore def > STR"
Do note that, I already have 80% PDR before getting hyper stats. I also don't need other hyper stat as I mostly max %cr, %status resist, etc.
