Yeah, I did indeed put it in the context of the entire Devon plot, because overall, the battle between Lin and Ame was just a small part of it - though admittedly one with some shock value, sure.
I won't deny that if you look just at the battle outside the context, then naturally it's meant to drive the point home that Lin is powerful. Point well made.
In which case: As far as my opinion on just the battle without the rest of the Devon plot goes:
Criticism has been aimed at how the scene came across like a poorly executed attempt at making Lin seem like a threat. And I agree! In a way. 'Cause I think the real problem here is that the scene was never meant to be overly significant to Lin's build-up as a whole. To me, personally, the reason it failed to leave an impact is because it feels like the scene wasn't originally planned to be there.
I just... don't really feel like the inclusion of Ame as a character in this plot has been planned far in advance at all. In fact, Ame used to say repeatedly in the past that she didn't want her character to have a significant role in the game, and that she'd just be the league manager. Just a side role.
Yet here we are, having her shown as the Champ, and then die at the hands of the big bad. How?
Well, to quote what Ame said on the E16 status thread (emphasis mine):
"However, as close to the end as we are with everything having been written out from the start, it's a bit problematic to just start rewriting things now. There are a few things I change here and there if I see a better opportunity of course-- and that may yet happen. It also may not. Who knows?"
And I feel like her inclusion in E16's plot must have been one of those short-term changes. It doesn't feel like one of those things that have been planned from the start.
If it had been planned a long time ago, then I doubt the scene would have felt as lackluster as it did to many of us, since surely, Ame would have remembered to build up her character a bit more in order to make the scene worthwhile.
it feels like it was just pushed in there, and as such, I find it hard to take the scene as something that's really supposed to be significant to the story as a whole. It's clearly there to drive the point home that Lin is powerful, but what Ame said about "opportunities" to change stuff sounds fitting here - it was an opportunity to get rid of the character.
