Obviously fan-made balance changes can be whatever, but it’s worth noting that if you want it to feel “official,” Sirlin has said that it is intentional that both Neutral heroes have no starting ability and one of them is tied for lowest max level in the game (5) while the other is tied for highest max level in the game (8). In both cases, it’s to make things more understandable for new players using the Starter Set to learn the game (don’t need to worry about an ability when you first summon your hero, and there’s a super-clear distinction between the fast-leveling but lower stats hero and the slow-leveling but higher stats hero while still letting them both have the same starting stats).
Since the primary function of the Neutral specs is to teach new players, I personally feel like any change that could confuse new players would be a bad idea. For example, Generalist wouldn’t change the balance of the Starter Set matchup at all, but it would make a new player ask a lot of questions that won’t be relevant for the match they’re about to play. I’ve always thought that tweaks to the mid- and max-band abilities on Troq and the Bashing spells and/or units would be the way to go, but there’s a delicate balance if you want the Starting Set to still be a balanced matchup, especially since Finesse arguably needs nerfed slightly for non-Starter Set play.
