And why should it be not? I just point out how could things turn out if SE putted a bit more effort into Minfilia. They only gave up on her because fans didnt want to see two loading screens to get to her, didnt like her attire and didnt like how she doesnt fight with you. But imagine if they decide to put a bit more effort. So, you have Minfilia who spent 100 years in the body of countless Minfilias in the First who fought and died, she gained wisdom and, I guess, power. Do you really think that after all these years spent she will be as useless as she was before rebirth, the same "pray return to Waking Sands" Minfilia? I highly doubt that. They could easily return her to the story and it would tie in perfectly: the long awaited reunion, everyone are happy, Thancred will stop being all butthurt, reunion with F'lhaminn. And Minfilia could be reborn being the more powerful and maybe she could even actually... fight! But no, lets create this cheap facade with ultimate sacrifice and giving a chance to a young girl. So meh.
And listen, what did you expect? I witnessed how a character I like became a victim of poor writing and backass storytelling. And I know just the ways they could do it better. What did you expect me to put up with it and not even let out a single whine about it on forums? Of course not.
I must admit, I quite liked your description of it. Looking at it this way actually made me feel a bit more comfortable around the whole thing. But I still have to say that thats why I love AD&D Alignments. You can play as a Chaotic Good character and don't care about stupid ultimate sacrifices, decisions between saving the world or saving the ones you love. It was with invention of jRPGs this crap became common and maybe after first dozen of titles such complex choices and stories were very interesting but now I just go meh at it. Like, again? Again its some noble soul who decide to sacrifice himself in order to build a better world/bring balance to the force/have a better legacy? Its such a well used trope this days it really became a mark of lack of better ideas. It would be such a breath of fresh air to finally see characters who only care about themselves, just like Chaotic Good but at the same time, fight bad guys and, well, save the world but with minimal losses. But not in jRPGs. Not with SE.
