I've always liked Generic Units since Final Fantasy Tactics and Ogre Battle. I usually have Generic Units in a class of their own compared to Unique Units, mostly because I rank the Generic Unit designs for how fitting they are for their class and just their designs in general while Unique Units designs I rank with their character/personality.
But I'd definitely try out a FE Game or even a spin-off where you have very little Unique units and have to rely more on Generic Units, whether it'd be through a Capture or Recruitment mechanic and whatnot, to progress through your game. You'd still have a Main Lord character, but there would only be 1 or 2 other Unique units.
And with Generic Units, you'd have to rely on RNG a bit, but at the very least, you can check to see their stats, what classes they can reclass to, and other things that normally the Unique units would have, but you'd still have to press your luck a bit with Growth rates. On the other hand, if doing a Recruitment thing, you could have a feature where by paying some extra gold, you can ask for those with good-growths all around or those with "potential"(meaning somewhat low-growth rates, but a chance of getting Aptitude or even getting a chance of higher-than-normal growth rates on a couple stats).
That aside, it'd be cool if they expanded on Generic units in future FE games and even Captured units. It would've been cool if the Boss Units you could capture in Fates had their own reclasses like they did their own growth rates.
No wonder why Dorcus is just a meme.
