I'm equally certain that those who verbally attack us mean us the Scions rather than us the individual character. I also have a feeling that any misinterpretation is due, yet again, to a bad translation. I would love for someone to pull those scenes in japanese and translate them so that we could get a clearer picture of what's actually being said. The Warrior of Light is someone whose upstanding character is admired, so I agree with you, and I would even add that because of this personality trait, we would not fight for something that we did not believe in. Proof of that is evident in the way we handle those who betray us: we don't hesitate to fight them. Btw, even outside of the cutscenes you can see who the Scions are in their ever-changing idle animations in Waking Sands and Rising Stones, and what they are outside of their quests and fights (and even in a few MSQ cutscenes) are adorable goofs who like to poke fun at one another and enjoy their off time like regular people.
I've barely started the DRK quests, though I did see a video of the level 50 quest, but speaking quite honestly here: what on Earth could the Scions have ever done to you to make you that angry and bitter with them in the first place?Speaking as a Dark Knight main, though, I feel you're reaching to associate the sense of being used that was presented in those quests as being caused by the Scions. No, it was very clearly building on the backlash of being betrayed in Ul'dah--a sense of being betrayed by the people we helped, as presented in the Lv 45 quest with the merchant who asked you to retrieve his goods, then turned around and tried to accuse you of having ruined them. It was the sense of ingratitude for what you'd done, not the fact that you had to do it--never mind that the flavor of quest being attacked was much more in line with sidequests than the main quest. Aside from the questgiver in the Lv 40 being afraid of you for "Frey's" outburst, there was no real negative consequence of saving the people there who actually needed to be saved.
