I added Alpha of Alpha to one of my stark custom much needed for sales I would say as it allows me to take more control of the frame when combines with Iron Frame.
Had the same experience, Stark makes me act way more (or work more), but Khan I get this social vibe and dominance which is pretty nice to feel. Run Khan on me and put me in a room with strangers, they wonāt be strangers for long. Stark I never tryed it in those circontances so I canāt tell.
