I was a bit wary of that one initially, but after I thought about it a bit, I am fully in favor.
Deliberately stringing out already won fights so you can run guys around and heal them was always degenerate gameplay that wasn't much fun. I'm playing spellforce conquest at the moment on the highest difficulty, and I'm having to do that lot because 'healer' units typically heal 20 health distributed among the party per day, but can also cast 5-6 in-battle heals for 30 or more, as many times as you can start a battle in a day. It really doesn't make a lot of sense.
Deliberately starting easy fights when critically wounded so you could heal was always kind of silly.
I personally hate the mechanic of having loot on a tactical battlefield that mysteriously vanishes into thin air after the fight if you don't pick it up, and thinking about it - this is kind of the same thing.
