RTF is a global modification that replaces all towns in the game.

Rain + Berserk – but against whom, a combat unit? By the time the hero’s turn comes, if there’s no Out of Turn (OOT), the troops will have already engaged, so Berserk will be much less effective. Berserk is even less relevant against a mage. Furthermore, the delay from enchanting arrows and using them can be (and should be!) balanced, thereby sharply reducing the effectiveness of Berserk, which becomes worse the later it’s used. For example, after enchanting, the hero can be pushed back 0.5 turns, and only then use the arrow. Mass Blindness is countered by mass Dispel or Meteor. Fantasy and realism are a separate topic altogether. I am one of those who believes that realism is the line between fantasy and just a fairy tale. Not absolute realism, but realism within some fundamental laws of the fantasy world.
