The Xbox store had Middle Earth: Shadows of War on sale plus all DLC for like six bucks and I’ve been playing that nonstop for the last few days

I’ve never played the game you’re talking about, but I’ve played similar ones. The idea is usually for you to experiment with different combinations over different play throughs to find powerful builds that match your play style. There are likely many potent builds, but the idea is to find the one that gels the most with how you play the game. Hope that helps!
