I hate it when the MC and crew are fighting the final boss, and when it's all "oh no! final boss is 2 OP!!"
MC pulls out last minute power that had practically no presence it was even a possibility except for maybe that foreshadowing in episode 3 so small you just easily miss it.
I mean power of friendship is still number one on my pet peeves, but come on least you could do is show that the rest of the party is there for anything but emotional support!
