What is an expected DPS or ratio to player damage I should expect for AI?

I downloaded the parse mod to see how much damage each of my AI companions were putting down. My current team is me as Zeta, and then Cag, Eugen, and Yodarha as teammates. I was averaging around 200-300k dps on proto Bahamut, and my teammates were all averaging around 50k max. By the end of the fight, I had almost double what the other three had combined. Is this normal? For those who have the parse mod, am I just clearly building these guys super wrong? Is there anything I should do differently then just try to build them around their normal human builds? Thanks!
