I think this right here is a big one. In early ARR, Minfilia is the one giving us our missions and assigning us to work with the various Scions. After Titan, Alphinaud joins the Scions and starts bossing people around. During The Black Wolf's Ultimatum, Minfilia is the one that opens the discussion with the city-state leaders, but Alphinaud keeps jumping in. When the Doman Refugees land in Western Thanalan during The Mother of Exiles, Alphinaud is the one that immediately goes off searching for them in Ul'dah while Minfilia has no idea what's going on. When the Doman Refugees are denied by Ul'dah, Minfilia figures that Mor Dhona is the best place for the Refugees and begins to make plans to contact the Adventurer's Guild there, but Alphinaud waltzes in and says he's already gone ahead and negotiated terms with them. Hell, Minfilia came across as sarcastic to me when she said that of course Alphinaud has already negotiated the terms and conditions, and she honestly seemed bored because he's busy doing his best to steal her job. Every time we're about to see her go do something, Alphinaud is there interrupting her or announcing he's already done her job for her. It makes sense, they're busy building up Alphinaud's HW character arc by feeding him a bunch of accomplishments so that 2.55 can hit harder, but it comes at the cost of actually seeing Minfilia act as the leader of Scions, negotiating terms, and working with the city-state leaders. I wasn't around in 1.0 but apparently she was more important and more active there, but even I was disappointed to see SE effectively write her out of the story. She was the founder of the Scions and it feels like SE did her dirty.
