The thing that consistently drives me nuts in this as opposed to, say, Warriors Orochi 3 Ultimate, is that the rest of your guys are goddamn retards. If you don't take care to wipe out every single base or whatever those little rooms are along the way, just one is enough to respawn enemies that will eventually overtake any bases you have taken, and then, in the end, your fortress (whatever it's called), and you lose the mission.
It's a pain in the ass when you're trying to kill the boss that just so happens to have an attack that can hit your fortress from across the map and you realize oops, left one little band of dudes alive that's also attacking it, it's going to fall. In 90% of the missions, you HAVE to wipe out every single enemy, which isn't the case in a normal Warriors game.
It's still fun playing as Zelda characters and the weakpoint system is interesting, but the complete inability of your allies to protect the fortress is super annoying. Also makes missions take far too long- average 25 minutes or so, average mission in a Warriors game is 10.
