@Sulla:
I agree on the Critical Hits part. That's really frustrating.
Random Level up usually gets evened out along the course of the game.
Night maps and Reinforcements are great, because they force you to move your weaker units along, instead of keeping them back. Usually these reinforcements or "hidden" enemies cannot kill someone right away, unless you place them right at the edge of the fog.
I never spend one second thinking about Biorythm. I always check the stats before the attack and if Hit is too low, I will attack with someone else.
Battle Saves: Well don't save if you feel it's like cheating. For less experienced players it's probably a good thing. I didn't make much use of it, because I want to finish it the "old" way, but if you don't care for that saving is a nice option.
EDIT: WoW do you have a link on the RNG?
