Heroes 5.5 WarGame Edition - Tactical Edition.

Nargoth has a strange dependency: the strength and growth rate of creatures are not linearly related. In any case, weaker creatures will be on tier 5, while those with high strength but a lower growth rate will be on tier 6. Similarly, for other pairs: making creatures of different tiers but with the same strength or growth rate from the same castle seems illogical and detrimental to the game.
