I suggest introducing a system of neutral creatures from Heroes 4 into Heroes 5! Details: In Heroes 4, all neutral creatures – those that cannot be purchased in a regular town – belonged to a specific faction. Let's consider three towns from Heroes 4: Nature, Death, and Chaos. Death has neutral zombies, ice demons, and mummies; Nature has elementals, leprechauns, satyrs, and mantises; Chaos has troglodytes, beholders, and trolls.
In other words, it could be implemented so that neutral creatures in Heroes 5 have not a neutral symbol under their feet, but the symbol of a specific faction, and, accordingly, the rules of diplomacy and other concepts would apply to them. :cool:
