Monsters degrade pretty easily and are point costed as if they always fought at the top teirs... BoC monsters are has tough as 14 gors. That just isnt tough enough. I actually think if they added 50% more wounds to most monsters [not every monster] and changed the degrade to start when they hit half wounds instead of quarter wounds.. It would make them viable..
Gorgon
14 wounds > 21 wounds 50% more
Wound degrade after it suffered 11 wounds
Would degrade again once it suffered 16 wounds..
I think monsters are so easy to degrade people arnt worried about charging them and either killing or making them hit like a wet noodle.. Where more wounds means even a good unit might not degrade it and suffer one attack phase at the monsters full power..
Also just changing nothing but monster degrade at 50% instead of at 25% would help alot
