I haven't played with the character yet, but honestly the dual identity thing is the main thing that made me immediately want to build a character. It's actually kinda fun if you embrace it. My social side doesn't wear the Belt of Mighty Strength, for instance, or several of my AC items. My vigilante wields a warhammer, but that's to bulky and obvious for my social side -- my social side only has a blade boot and a sap.
Granted, I'm using the Avenger specialization. It seems from reading that a lot of the complaints come from people looking at the spellcasting options. Maybe it's just one or two of the specializations that are really that off?
