I tried the new demo update with the dwarf mage and here's the review:
When I first saw the dwarven death machine I was so surprised by the 20 20 stats but then realized I didn't check the speed. So speed is 0 first then can be buffed by guys later and health can be buffed too. Then when I found all that out I devised my strategy: kill all the buffers for the death machine and prioritize the speed buffer. Then get some strong units and kill the mage while mostly avoiding the death machine.
Things I want to change:
The death machine can be killed, and that's fine, but where it respawns is different. When I killed it with taken by the sea I noticed it respawned in the same spot, which I think could be changed so it has 5 positions around the dwarf mage instead of just one spot.
I also think in general the ai could be updated so that if any mage is at critical health it either tries to kill the player fast or kill the attackers first.
