but what about the sets for merc?

a pretty interesting idea. possible sets would be: Berserker's Arsenal, Isenhart's Armory, Milabrega's Regalia ( is act 5 merc able to wear shields?), Heaven's Brethren (maybe someone will miss the crown), Hwanin's Majesty (delete the belt make it better and you have a perfect act 2 merc set.), Sazabi's Grand Tribute

not as good as elite sets just good for supporters.
