Absolutely and I wholeheartedly agree w/ you.
The issue with OTWTAS and ACC, as many people have pointed out before me, is that it's basically a redo of Cloud's arc in condensed format w/ bad execution. While there's nothing wrong with Cloud having to re-learn that he's not alone/doesn't have to do everything alone, it does trample on a lot of his already established relationships. It almost feels like, "woops, we kinda forgot to show Cloud grieving and feeling sad/guilty in OG so... here he is doing that now!"
And my complaints are never that Cloud sucks, but rather that the writing sucks and it fails a lot of these characters. I had completely forced myself to forget the scene in CoT where Barret tells Tifa he's going on a journey to settle his past and when she says she wants to do that too, he tells her she needs to stay home and raise Marlene. It's basically like "No, you settle your past by being a mother to MY child, thanks." And that's so OOC for Barret now. Just like Cloud knowing about Barret wanting to leave and not sticking up for Tifa's right to be involved in this decision is OOC for him now too.
A lot of the behaviour that sets up ACC doesn't even make sense for these characters anymore, and in fact Nojima has gone out of his way to undercut his own writing for ACC--which is very interesting. In ToTP, Tifa is adamant about the fact that she will allow no one to decide what her life will be or what it will look like yet in CoT, Barret and Cloud do just that. And this makes me sad, because if all of that stays canon that's so damn tragic for her character.
