[SPOILERS] Shadow of War Act 4 Frustration

Am I the only one getting irrationally fucking angry at Shadow of War's Act 4? Seriously, this act alone is making me hate the rest of the game.

• The story is pointless as all hell, it should have ended at Act 3.

• Repetitive siege and defense missions

• Extremely overpowered enemy orc captains who siege you that are 10 levels higher than your defenders.

• To level up your warchiefs you have to first take them out of being a warchief, and then send them to the pit where they might die, then send them back. Super annoying if you wanted to grind 5 or more warchiefs in a session

• During siege defenses, enemy orcs and caragors literally swarm you non stop, while enemy warchiefs interrupt you every 5 seconds with a 15 second fucking monologue, stopping whatever Talion was doing, and pretty much fucking you over so orcs just one shot you. (This is probably my biggest problem)

So yeah, this might seem like complaining about the game being too hard, but Acts 1-3 were perfect for me in terms of fairness and difficulty. Act 4 just seems plain old fucking cheap and unfair, to the point where it's not fun for me. I would like to see the true ending of the game, but I don't know if I can suffer through this. Thoughts?
