The plus is that the battle map becomes constant (as in Heroes II), and the battle can always be repeated according to its description.
The minus is that the game will never be the same as it was originally intended by the developers (the system for dropping battle spirit/luck is fundamentally changed).
I am writing this because there is an urgent need to adjust the rules for offline games (tournaments) in Heroes III (and possibly online). And we will have to decide what changes will be made to these rules, taking into account all the nuances that arise.
Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up,
Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil;
Rejoiceth not in iniquity, but rejoiceth in the truth;
Beareth all things, believeth all things, hopeth all things, endureth all things. Charity never faileth...
