- Designers working on FPS games that have never played an FPS

Not necessarily a bad thing. Goldeneye was made by a bunch of people who had never worked on a FPS.

Oh, hang on, you said "played" not "worked on". That's a real problem. 

But still, my point stands though. It's ok to bring people in from different skill sets and backgrounds as long as you have strong leadership and a laser focus on the kind of experience you are trying to produce. Too many of these ubi games are just "This, but online" or "That, but open world".
