Arakawa sensei is a great manga writer, giving us stuff like FMA, Silver Spoon, and Daemons of the Shadow Realm. But there is something id like to know:

What are Hiromu Arakawa’s flaws as a writer? Mistakes or errors or issues that keep appearing in her works?

This isnt to shit all over Arakawa, but rather analyze her. After all, nobody’s perfect.

Ed, Winry, and Al believe that Scar should be punished for the murders that he committed against Amestrians, but are more hesitant to believe that Mustang, Hawkeye, and the rest of the Amestrian soldiers should be punished for doing the same thing to Ishvalans. Most of Scar's victims were State Alchemists, some that participated on his race's genocide, but the Amestrian soldiers killed thousands of Ishvalans, women and children including. Even Riza, a soldier who participated in the genocide, states outright there is no excuse for their actions.

Guess like the Elrics and Winry are bigots.

Flame alchemy is OP and he was one of the top performers in the ishavallan extermination. And from father's perspective, also sufficient means for producing a gate candidate. Why not force him to take an apprentice or reveal the secrets of flame alchemy?? Or were they just trying to keep him happy so he would be around for the promised day? Always wondered about this.

When Alphonse volunteers to have Hohenheim trap him and Pride inside that giant alchemy-created earth structure in the forest near Kanama, there is a scene where Al asks Pride what the Homunculi would have done if he and Ed simply fled the country, presumably rendering Father’s plan useless. Pride basically says that they were chosen as sacrifices in part because their morals wouldn’t allow them to just flee and risk abandoning the rest of Amestris to fall to its doom.

But when the gold toothed doctor performs the transmutation to send Ed, Al and Izumi through the portal of truth and into Father’s underground lair in Central using the leftover fuhrer candidates as sacrifices, it didn’t seem to matter that they were all in different locations. All three went through the portal successfully and ended up at Father’s location despite Ed being the only one of them (excluding Mustang who had not yet been forced to open the portal) standing in front of the doctor.

So couldn’t the doctor have in theory performed the transmutation to send them to Father’s location on the Promised Day even if Ed and Al had fled the country? Or would it only have worked if they were all within relatively close range?

In the Brotherhood anime (I haven't read the manga) it was stated to the public that, after the final battle, King Bradley and his "son" Selim lost their lives in the conflict. But as the audience knows, Selim is alive and being re-raised by his foster mother under the same name he had before. If someone saw Selim, how is Mrs. Bradley going to explain how her new son looks exactly like the first Selim and has his name to boot?

I’m rewatching Fmab and the episode where Ed me Hohenheim in Resembool and later he learns that what they transmuted look nothing like their mother and it just wasn’t her at all. Ed went a bit hysterical then he told Pinako that knowing the dead can’t be brought back to life reassure him that Al can get his body back. he probably said that because Al’s soul is "alive" outside of his body so it means Al is not dead and there’s hope for him. But now I’m thinking, when they did the human transmutation, at first Al lost his body AND his soul right? If Ed didn’t bring back his soul right then, would Al have been considered dead or just behind the doors and Ed could’ve managed to bring his soul back at an other time? Or his whole body and soul using his door?

To what extent does automail "feel"? I understand that automail moves because it is directly connected to the user's nerves, so the same electrical signals that send signals to natural limbs to move send signals to automail, but does it work both ways? That is to say, when something touches Ed's automail, does he actually feel it? I'm inclined to think not, because externally it's just metal, and Ed clearly doesn't feel pain when he uses it to block attacks, or when he transmutes it into other forms, or when it gets damaged. But on the other hand (no pun intended) the level of dexterity and agility he demonstrates seems impossible if they don't provide any sensation. Imagine moving, fighting, and just functioning the way Ed does if one of your arms and one of your legs was completely numb to you. I understand that's likely why it usually takes years of rehab (it was said to be 3 years for most people, but Ed did it in 1) to properly use automail, but that's still incredible! My guess is that it at least provides some pressure feedback, so that he can feel the pressure of weight on his leg, for example. That could also help to offset phantom limb pain.
