Just finished chapter 5. This campaign is much better than Human one. If you keep improving your skills, the Orc campaign will be awesome

My comments for chaps 1-5:
1 - just a copy of
Blackrock & Roll, Too! map, even the same quests

However, I really liked Tichondrius's abilities (though they're a bit op). They're simple, but really... nice

.
2 - My favorite one so far. The Dark Conversion is really fun ability. At first, I thought it would be too easy to preserve 100 zombies, but if you want to kill red heroes, it's absolutely fine. Just one thing: zombies that turn against Mal'Ganis are invulnerable. Is it intended?
3 - Another copied map. Nothing much to say here.
4 - Well... I don't really like this map. It's just about destroying 3 bases, you should add something more exciting here...
5 - At the beginning, I thought it would be really similar to the chap4. However, it turned out to be quite nice. Green areas here are truly unique idea. I would never think up it

. However, I hope you'll explain why the Green Dragons are here (maybe in NE campaign?).
Oh, and the last thing: Bloody's ranged attack looks a bit weird.
I'll comment chaps 6-8 once I play them.
