I get the idea behind this faction. It's snowball-ish and once you get the engine running the power ramps up. The problem is that on 150% and 175% the neutral stacks are more powerful and you get less resources to spend on what is the worst T1-3 unit rooster in the game.
Wights have the stats of T1 unit and are completely garbage before their update (which btw you can't get together with skelly archers because of the dust cost). The dogs barely have the stats of a T2 unit despite being T3 and the first decent unit the Graverobber is gated behind a cost of 5 Mercury AND 5 gems. The skelly archer itself is nothing to write home about either, since due to its low initiative most other T1 units are able to close the distance quickly.
The entire faction is constipated by this massive early game weakness. There is no solution except luck with starting spawns and free resources. Was the game tested only on 125% or lower difficulty?
