DON'T HIT TOO HARD!
and here's the suggestion: IMO, if saving and reloading during battles is prohibited, the offline mode will be much more interesting and less tedious.
For example, there might be a need for a specific, probabilistic event to occur 10 times in a row during a battle. Let's assume the probability of the event is 0.5.
With save/load, achieving such a sequence is not difficult – 20 cycles.
Without save/load, it will take 1000 attempts to play the battle "in one go."
That is, we will get the same hassle, only much earlier, in the simplest battles. Does anyone need that?
* - I'm not being too harsh, I swear :)
