100% leave the imaginative to us flesh bags but stat balance could definitely use a mathematical and mechanical touch.
Not surprised to see gameplay take the lead here. It's such a teeter totter in my view. Take old orcs and goblins, they were very "thematic". Heh. So much so it affected a good deal of balance, gameplay, and enjoyment.
I'm very curious to see where Kruleboyz go for 4th when it comes to gameplay vs balance. The bits of rules we've seen have somewhat turned their theme upside down; killaboss ability is void with no battleshock, everyone will be "poisoning" on 6s, etc.
I still think that middle ground is achievable with fun and thematic rules and still knowing through tactical ability that you've got a good chance of winning.
