Which Might and Magic universe are you referring to?

Inferno, in the third game, is only connected to hell by its name. It is a faction of alien invaders (Kriganes), and most of the units are the result of experiments.
Rampart is not an alliance of forest creatures. It is the elves of AvLi and Vori, fighting through the animals they have tamed; there are also a couple of allied peoples, but that's all. And there are only two elven units there – elves and pegasus riders.
In the factions, you didn't even mention the chaotic nature (moreover, you criticized Inferno for its "low chaotic nature!"), but only expressed a couple of phrases in the spirit of: "I don't like it!".
