@thevhswizard In my opinion, 3 or 4 is hyperoptimal in case you want to keep your players' life easy or dare i say casual (not in a pejorative sense). That said, I played FGO with a very wild strength/weakness chart (attached few of them as they evolved through the time), sometimes it's a bit confusing, whenever you have to a weird lineup you can't cover completely, so you have to risk, but it also could be worth exploring.
