I was hugely disappointed by that, as she had been introduced as a superhuman polymath, learning languages, electronics, spycraft, chemistry, musical instruments *and* fighting styles and gymnastics, and then sort of stealth-retconned into being only able to replicate fighting styles and physical stuff, to make her more like the Taskmaster. She went from being completely original, and with unlimited potential (including to be one of the rare, at the time, ladies to enter the 'top 10 geniuses' list, years before it was flooded with Riri, Nadia, Lunella, etc.), to a less-interesting version of the Taskmaster (which 616 already had one of, with Melee, from the Initiative, who Taskmaster expressed an interest in sparring with!). Ugh.
I wish we'd see more of Finesse, even if she's been massively downgraded from 'master of anything she studies' to 'Taskmaster 2.0.' I liked her practical streak, and how it made her a bit less innately heroic than some of her peers (like Reptil and Mettle), and perhaps a little too well-suited to slide into villainy, if not given a logical / practical argument to be on the side of the angels.
I wouldn't mind seeing more of Reptil and Striker, for that matter, or some of the Initiative kids (Komodo and Hardball, for instance, or some of the lesser seen people like Red Nine and Telemetry and Gorilla Girl), or some of the many cool teen mutants that have been mostly forgotten (Hellion, Dust, Indra, Loa, etc.).
Really, Marvel's just got way too many characters I'd like to see more of! It's pretty much the definition of an embarrassment of riches.
Maybe what we need is an Avengers version of Generation X/Wolverine and the X-Men - a book with maybe eight or so regulars and a lot of others appearing as and when the plot calls for it. But they'd have to call it something other than Avengers Academy due to the mobile game.
