I played two games; I like the addition of the campaign heroes though I wish each hero had actually unique spells. One game I played with Grom and just spammed out Grunts and Raiders, and another I played with Garithos and spammed out Footmen and Knights. Very thematic.
The map has a great idea, it's just the execution that could use some work. As an altered melee to play in your free time, it's very fun, and the items clearly have work and creativity put into them. I don't know if the terrain is unique/made by you but it looks fucking sick. I wish we had some melee maps on ladder with this amount of detail.
I noticed the tome spawners only create Tomes of Agility and Tomes of Agility +2, and looking in the triggers, that's probably a bug.
