With a pocket WHM you don't even need to bother with the Evasion and -pdt sets save for when you get to 99 and have made considerable progress through Abyssea. Even then, if your WHM has half a functioning brain you've got nothing to worry about, and if you're ever in a situation where something is hitting you that hard you've likely got fanny/fool's tonics at the ready. For everything else, there's cureskin. :3

Seal NMs go squish. Have fun with that.
