Sorry for how sporadic these seem, I'm a bit scatterbrained and act impulsively on some things. That being said, I have some more information to offer. That said, this is another update to sorta rectify what I said previously.
From some of the reviews, and my own personal retrospection, I've thought about some of the major flaws in this fanfic I made.
First off was the set of servants. Looking at the seven that I chose, it became ever so clear to me that it was going to be a landslide victory. Pretty much all of the servants, revealed and not revealed, had aspects of divinity and mystery to them. In other words Archer, aka Oda Nobunaga, would've probably mopped the floor with all of them. Even Issei, with the Boosted Gear, may not have been able to beat her. Not saying that he isn't strong, just that they're not compatible. On top of that, I didn't think some of the pairings I did were very good, and probably could've been better.
Second was the involvement of the Holy Grail War and the devils/angels. I think I could've planned it out a lot better than I did. That's another thing I'll be thinking about during the planning process.
Fate/DXD may very well be rewritten. Although it will likely have a different set of heroic spirits. While working on my other story, i'll be doing some research on different historical myths and legends to figure out a more interesting story to work with.
That's all for now.
