Oh okay, so you're the one who determines whether people's opinions are stupid or not.
Once again, cute effort ...
But if you read abowe, you can see this:
If anything, I feel like people are bending over backwards trying to find reasons to hate.
+1
Do you know what that means? :P
"I" was not the judge here ...

:P
No, but you +1'd the person who decided they were the judge, didn't you? I don't know what +1 means in Czech, but in the languages I do speak, it does not typically mean "I completely disagree".

I really honestly and without a single doubt concider "whole Shadowhearts setup being wrong" as much bigger narative problem than the fact that Aradin yelled "form a line" while there was only two of them to form it.

Obviously the "form a line" thing is just a momentary thing of very minor importance, a small wrinkle that feels a bit daft but whatever, whereas the way Shadowheart's narrative is played has a lot bigger impact since it's being done over hours and affects a major character. Obviously there's a difference.
But for the purpose of "weird things that makes one cringe", wouldn't you say that a somewhat seasoned mercenary commander telling his one remaining melee grunt to "form a line" is a bit silly? It's like having a Roman commander tell his one surviving legionary to form a testudo. An order to "form a line" delivered in good form, with authority, sounds like something a combat veteran in command might say, but the comment doesn't fit the actual context in which it is being used, and the actual execution of said line doesn't help. "Form lines" or "Form up" or "Hold the corner" would all have worked a little better, particularly if he'd then also held the corner with his grunt and kept the gobbos off the archer.
But yes, this is indeed a very, very minor thing. It's still a bit silly, though. At least I personally think so.
