Problems with Heroes of Might and Magic IV.

I also don't like the simultaneous attacks in the 4th game. While simultaneous strikes are understandable, it's strange when, in a single moment, titans retaliate with the "saliva" of medusas. If this process were sequential, there would be no questions)))

all the creatures I mentioned look as if they have "balls" that are too big.

Maybe their "balls" are indeed big, like those of bad dancers - but there's no way to check. As for the archers, it's quite realistic - a unit won't be able to dodge or defend against a volley of arrows, but it will try to shoot first to inflict damage and reduce its own losses. Unlike infantry, archers have both hands occupied, so they can't hold shields.
