SMN is great. (or at least the horn and pigaches are... empy+2 body is still better... even if the +BPdmg% is the same +10%... the pants don't beat Ngen Seraweels or the Empy+2... and the hands still can't touch relic+2 bracers...)
It's pretty much the same for all the others I'd imagine... Though I've only looked at WHM and DNC... And DNC because the empy set isn't anywhere near fa~bu~lo~us enough for me...
1-2 pieces that might be used... mostly mage oriented jobs will use them over the skirmish or even bayld gear.
But overall from the three I looked at, very nice.
Which shouldn't be all that surprising because GEO and RUN's 109AF1 sets were very well designed.

But it sounds like getting the "seals" to get the pieces you want... is gonna be crappy.
From what I gather, it's X of a certain numbered Memoir for a certain piece. X is less for a AF1+1 piece

This is very tentative and likely to be wrong... but with what I got now.. this is how it be.
