The problem is more that
1) ice is harder to spot than fire
2) characters won't always path around ice, they WILL always path around fire
3) the only punishment is that it wastes your time. I'm okay with taking damage, I'm not okay with my time being wasted.
Yeah the pathing around fire rather than ice is a bit irritating. On the other hand, I had no idea one could slip on the ice until having done it after a battle.
