It seems strange that winning a battle very fast gets you more Experience for each unit, even if you've not killed most of the enemy army (from what the manual says), but i'm pretty sure one of the tips says finishing a battle too quickly might mean your units get less Experience for killing other units. Which is it? Or are there two ways units get experience, some from what they do in battle and some from how quickly you win?

Personally i'm not keen on the time limits - destroying the enemy forces completely, capturing objectives and avoiding casualties on your own side should be what matters imo
