There's indeed no point in not putting the healing to max and enemy damage to min but you still have to remember to do it and with the timer there's sometimes misplays on those. Plus, in the 2nd campaign some enemies have abilities that do more damage if they have low dices like : "18-TOTAL DAM" so you have to read carefully and not put every enemy dice to low score.
The first campaign only have simple effects because I didn't want people to be confused but unfortunately the 2nd campaign is a bit buggy so you can't enjoy the game at its best.
Thank you for your idea it's a nice design but I think that it would have been too many mechanics for a jam game.
