Did I read that right?

That would suck horribly Tech, You need scouting to learn Reserve so you would already know a troops composition, so short of the rare ambush/npc initiated/keeper fight - (where you could use save/load anyway) you would never use it?

Now if it meant that if a stack was killed you could bring in a reserve stack - holy smokes that would be amazing! But that leads to more questions - reserves can have any leadership etc.
