We thought about that. But the game became too easy to play. And it's not as RNG heavy as you think. There's an algorithm that generates what dice you get, it's not 100% random. Sure the dice rolls feel random and your perks feel random, but you don't need any more control to have fun with the game. Infact, the more we removed control, the more fun the game became.
It's a very simple concept for a strategy and there's not much depth to it. If you remove the randomness, the game would feel very simple and boring.
