Totally. I can only hope my worst fears are not realized for a while longer.

Sasha obviously had enough good points to endear her to many, and that's what spared her from her original ending. And she could be even greater. And as I said, Jean and Connie too could easily be greater than they have been allowed to be. But I honestly do not think Isayama excels on that front, he's focused on the ones who are really rolling the dice, and has always neglected supporting characters. Sasha isn't a special case, as I said. He should've found more to do with her and the others, quite a bit more. And they all have a following. So there's no excuse for being so lax. Or for not bringing some fresh blood into the main cast that actually can survive more than one arc with actual individuality to show for it. That did make the loss of the Special Operations Squad worse in hindsight. I'm sure there were other ways to establish Annie as a nasty force to be reckoned with without all those new faces who were really coming into their own. Because Isayama didn't really do much to fill the void, and every new face just ended up another redshirt.

Even acknowledging the nature of this anime, that's still managed to work against it.
