They can't boost the stats on the 1H weapons because you can equip a shield with them and it would give them a distinct advantage over 2H. On that note however, I would like a response on this as well. At least the i95 buff will plant the scepter firmly as BiS with the crafted shield on offhand, but it will technically still lag a teensy bit behind the rest. Oddly, PLD is in a similar of not as critical a place after the patch assuming the Allagan Round Shield isn't buffed to i95 (Turn 1 drop and all).
