I also use the Necropolis tactic, setting it up before the battle. However, I send reinforcements to the archers, as I don't have many units yet.

You can never have too much healing, but regeneration is a weaker form of healing. As for "Aggressor" and "Defender," I disagree. There are already plenty of buffs in the Campaigns, and these are just a waste of skill points. It's better to learn something interesting from magic instead.
Of course, you usually use healing, but sometimes, for a lossless game, it's good to have something you can cast after healing. Although, for the Alliance with two units of Adepts + Seraphim, it usually doesn't come to regeneration...
I didn't mind spending 1 point on +3 to attack or defense, as after level 25, there wasn't much else to upgrade. A Warrior with his magical power doesn't get much benefit from magic. And the first 2 levels of magic don't offer much... I took "Taunt," but I only used it once during the entire campaign – just to see what it does. I also took "Fear," but it turned out to be unnecessary; 95% of battles were won in 2-3 rounds, following a pattern: push the enemy, heal your own. In special cases, I used "Forward" to attack immediately, and I also summoned Phoenixes against archers.
I leveled up reinforcements to level 2. Seraphs weren't useful, they were too expensive :)
I leveled up a lot of chants to gain blood/tears faster, taking cooldowns into account :) I shouted everything I could, even when it wasn't necessary :)
Magic - only healing (if it's a warrior - there's not enough mana).
100 mana is enough for one cast of general and individual healing).

I gave him the Griffon Sword myself (which is also good). I just set the goal to max out this sword as the first one obtained in the game.
