Balance in Heroes 5.

Yeah... Calling "Warrior" the most balanced difficulty level... I won't even be lazy and will describe the levels:
Warrior - the computer-controlled hero doesn't use spells higher than level 3 and moves its units in such a way as to reach the enemy as quickly as possible. Target priorities in descending order: melee creatures, flying creatures, ranged/spellcasting creatures. At the same time, the computer player is given only 10,000 gold, 10 of each common resource, and 5 of each precious resource. The human player has exactly three times more. And the computer player only builds every other day.
Veteran - the computer-controlled hero can use any spells and aims area-of-effect spells more skillfully. When moving its units, it takes into account the position of the enemy units so as not to be exposed to attack prematurely. Target priorities in descending order: flying creatures, ranged/spellcasting creatures, melee creatures. The computer player builds every day if possible. It also hires more heroes, but this is not so important. The computer and the human player are given the same amount of resources.
So, which level is the most balanced now? You still have a lot to play. And in general, go to the fаnDocumеnts folder in the game folder and learn more :-)
