I am making my way through Yakuza series right now and while playing 5 I realized that I am not that invested into the game’s combat, so I turned it to easy and that just streamlined the combat so much for me. I would recommend to maybe try Yakuza 0 on normal at first and then just switch it to easy if you feel like the gameplay might be dragging on.
Maybe it’s a skill issue, but this game was Star Wars Jedi Knight 2 for me. I think I played it on the second easiest difficulty. On higher difficulties, the enemies move much faster and do more damage, and you start to realize how inaccurate the guns are. On top of that, the weapons are projectile weapons, so you’re aiming inaccurate and slow projectiles at stormtroopers shuffling left and right rapidly. I think it’s much more fun to just play on the first or second difficulty.
