lol. That's way too on the nose/fan service for Monolith.
That's the kind of thing that should be DLC though, since it avoids the impression that they're cutting characters from the main game.
DoA5 being bad with DLC doesn't really make FEA good with DLC. I kept up with it out of foolishness and love for the series. That doesn't really make the content they offered (repeated and simplistic maps, cheap banter from npcs that don't really add anything, characters without any supports and are inferior to the main game's cast, character art cutaways with the scramble packs pandering to the worst parts of the fan base) actually good or substantial. What they offered is pretty overpriced. Like the only half decent pack is probably Future Past.
The Scramble packs add ton of dialogue though. It's not like they only exist for those fanservice pictures. Of course, I guess it's only valuable if you actually enjoy the game's writing and supports, and considering your tone I'm not sure you did. Aside from Future Past though, you've also got the pack 3 challenge maps with unique obstacles, and then Apotheosis in order to have a battlefield for a completely maxed party.
Now, like you say there, the first four packs were rather cheap in several ways, like the recycled maps and cheap characters, but they were basically bundles - you had the stage, character, unique conversations with each npc ally in the map (and also with each enemy if facing them with a specific character, although those are really short), and sometimes new skills and even two classes. Some of them also are better for leveling up higher level characters than the proper exp map.
