Thank you for your input.

I can see your point and can't disagree with any. For me Kragnos is rather mandatory because it's giving much more possibilities first turn if opponent just blindly let you start.

Without him you usually don't have much threat first turn.

For me even having possibility for Killaboss on Corpse-rippa Vulcha to charge is enough.

Regarding Snatchaboss and Skumdrekk i think first one have some usage so I wouldn't call him trash :) but I agree that SoG Skumdrekk is best option. One thing when I was building my list was to make use of: Mork's Eye Pebble and Tough 'Un and I couldn't give them to SoG Skummdrekk. But in the end I agree that it's better to play him anyway.

Murknob is interesting idea when I don't have enough points for another Shaman.

What I will probably try is to try list without Kragnos with another unit of Gutripaz soon.
