I think most of us are fine with Stella getting huge and bossy. The "controversy" comes more from her getting huge through "cheating with drain magic that Gina just hands to her for free" and kind of being lazy at the gym vs training hard like Gina or Jade. That being said, Don told me it was intentional to snowball the effect with the other girls so I respect the decision.
As for unpopular opinions, I actually like this FMG game more than any other because this is the only FMG game I've played where the muscle girls go toe to toe with super muscular men. Usually the guys are just average and weak in FMG games but having the girls needing to muscle up to go against huge guys, makes their achievements that much cooler for me.
