This isn't a git gut situation. because the entire gameplay loop is "encounter an enemy, lose a fight, go somewhere else, gain a level, go back to the same enemy, kick their ass so hard there should be an achievement for it"". The window where tactics actually matter is fairly narrow. Most of the time your stats decide the outcome.
Yes, it's a delicate balance design-wise, not easy to maintain. There are things you can do to make the mechanics more stable, though.
