1 of all people to go on death missions he picks the one who can heal any injury put mipha in the medical field not a battleground
2 instead of making link pilot a divine beast since he has combat experience he chooses mipha who has little to none imo thats dumb
3 if they want to beat ganon then why hide the master sword the only thing that can beat him in korok forest the least safe area since its swarmed by monsters and the only defense is a tree
4 they put no defenses within the divine beasts none at all they could made it so theres an anti gloom force field or turrets that disperse gloom but no spend all of the research on lasers that dont even kill ganon
5 if they want zelda to awaken her powers then maybe give her better training then reading books and looking at frogs all day goofing off with link
6 if they want the castle to be safe maybe idk hire swordsmen as good as link instead of fodder soldiers
