I just accept it as part of the fun and part of the tactical play to avoid being on fire and low health at the end of combat.
Unfortunately this was frustrating enough for me that without this function I will not buy D:OS2. I don't find it fun for my party to all die because the enemy nuked himself before I could heal myself during combat. I also find it annoying to have to leave one enemy alive while I spend each character's action healing themselves. This is a simple fix that will make the game less frustrating for some people (myself included) as well as allowing more tactical play, I just don't see a reason to not implement this.
