To be fair, I defy you to find a game that lets you save mid combat. I really cannot think of many (some, but certainly not many).
…I get the whole wasting my time argument… but hey, welcome to the world of gaming!?!?! F*** I don’t even wish to dwell upon the amount of minutes, hours, days and years I’ve wasted playing video games. But do I care? NO!
From personal experience you can either have a life, or play video games, theres not much room for both ;)
Jokes aside, I wouldn’t have a problem with saving during battles; so long as Ironman mode saved after each and every combat turn.
