If you have an investment in the tactics skill you should be able to remove friendly stacks before battle (so they don't participate in that fight only, but return to your hero when the fight is over). This allows you to remove vulnerable stacks while creeping that are a liability (e.g. a t7 unit bumrushes that unit where you would otherwise have zero casualties).

I believe this was a feature of one of the heroes games after HoMM 4 (maybe 5, but possibly 6 or 7).

Before early access is over, it deserves a redesign. It's a skill all dungeon heroes are forced to get that amounts to +6 in one stat when you fully max it. It's just nowhere near as impactful as the other factions primary skills.

Not only that, but it's also really boring.

If you're going to go with the dungeon theme of flexibility (like fighting styles), just pure stat increases are really boring. Why not make it so you have three options that actually change the mechanics of battle. I'm not a game designer, but as an example, option 1 could be to make it so you pick one enemy unit and remove its retaliation for the round, option 2 could be where you give a friendly unit one more movement turn but it can't be an attack (so a quick retreat or get out of range), option 3 could be something influencing spells, like making a spell last longer or allow for a second spell cast that can only be a lvl 1 spell or something like that (to differentiate it with thaumaturgy). These are just examples, it could be anything. Pure stat increase is so boring.

On that matter, maybe make all primary skills for all factions optional (meaning no heroes or most heroes don't come with it).
