Your characters won’t all level up together

One of the more frustrating things about Persona 3 Reload’s preservation of the original game’s constraints is that your party of 10 characters does not all gain exp if they’re not in the party during a battle. In theory, you could settle on a group of four that you like and keep them around without having to worry about your benched team, but Persona 3 Reload will have some characters rotating out of use because of story developments. So you might find yourself down a key player in your strategies and have to tag in someone who is far weaker than the enemies you’ll be fighting. You can avoid this by rotating your team throughout the game, but whatever you decide to do, know that keeping everyone around the same level will be a major grind. You will, however, reach a type of room in Tartarus where you can level up characters to the protagonist’s level, but this will be a limited resource.
