Your suggestion would change the whole game. You can increase the DC of your spells later to nearly 30 so even playing on Tactitian is not a problem. But you are right sometimes the battles are unfair because you of bad luck. But i finished the game twice (sorcerer and Necro) on tactitian and now i think the game is to easy. Although i know there are many new players new in this genre lured by genitales and bear sex and for those guys the game can be really hard. So there are many videos on YT teaching the mechanics etc.
