This is like if Batman was somehow beating on Darkseid and had him dead to rights, then Superman showed up and finished the fight, and people started complaining about how Superman shouldn't have been able to beat Darkseid while ignoring Batman's role.
And if there's one weapon Mojo should be afraid of, its the weapon that specifically kills sorcerers.
I'm trying to understand why it's so upsetting that Mojo be afraid of one of the most powerful and scariest mutants alive, but Dani and Karma get a free pass for scaring him and easily defeating him.
