Yeah, I agree. Queen should have been a woman with a Bee DF (The Queen and her hive). Also I agree that Jack and Yamato should have been friends or like brothers. Kaido always wanted a male heir, and doesn't like that Yamato is a woman so he treats her bad while he treats Jack better. This could mean another motive for Yamato to reject his father and look up for a free figure like Oden.
