The new Orcs are impressive :). But let's go through everything in order.

On the official forum, one of the users came up with a name for the Goblin Shamans - GoShi :D. I will refer to them as that from now on :).

So, following the advice of the Pathfinder, I remembered this name "Goblin Shamans." I read a lot about them on the official forum. This is indeed a powerful and strong unit, and the astral attack is truly overpowered! Not only does it deal huge astral damage (which is obvious from the name), but it doesn't have a cooldown (it has three charges right away), and it DOESN'T COST ACTION POINTS to use! Thus, neutral GoShis kill one of my stacks (and not just mine, of course ;)) with three "Astrals" on their first turn, and wound another with their astral axe. But for every loss, there is another gain :). The new artifact "Crown of Chaos" blocks 50% of ASTRAL and magic damage! This is, of course, madness, but it should theoretically help a lot against GoShis. But I haven't tried it in practice yet :o.

Orcish Warlords are another strong unit. And Ogres, although they did it before, steal action points from the Emerald Dragons and attack the enemy from the first turn! Also impressive.

Orcish Veterans have become even more useful. Potion of Rage + Furious Attack = three defeated enemy stacks on the first turn. Hmm...

But the Rune Wizards didn't impress me. They depend too much on runes :(. And without runes, they are weaker than some level 4 units.

I haven't gotten to "Black Hole" yet, but I already have almost all the spells by the Spirits of Wrath in the form of scrolls. But I don't see any reason for their introduction into the game other than, indeed, nostalgia.

The Tower is a great thing :)! I easily passed the first four floors, but I got stuck on the fifth, but I think I'll come back later. And it turned out to be very interesting: it's a pleasure to kill free units against hordes of enemies :).

The Military Academy. I don't understand :(. The improvement in terms of trophies is INSANELY expensive, and reducing the number of units is absolutely not beneficial. It seems that I haven't figured it out properly :(.

But the add-on is definitely a success! This "small content" has significantly diversified the game. But it is clearly overpriced.
