I also found it ridiculous that how in the DBS manga Goku seemed to have no interest in polishing Oob into a true warrior, saying "Nahh, training like that isn't for me". This doesn't seem like Goku at all, really.
Goku in the Super manga also wonders whether Beerus has eyes in the back when he dodges a hit at a blind spot, which should be something Goku should be already capable of with his training with Popo.
Goku is dumb and naive enough to the point of not knowing what kissing means, even though in the end of Boo saga he was already smart enough to blackmail old Kai using a real woman (Bulma) and knew when not to fight stronger enemies, whereas in Super it seems Goku wants to take a shot at anyone no matter how outclassed he is.
