However, I can't hide from you guys that my favorite armies were Griffin and Dirz.
So you were a True powergamer
I remember this two faction as the strongest in times C3 - these two and Cadwallon.
But Dirtz was the strongest with mutagenic boosted beasts capable of destroying all main units in one turn.
Im really curious how do you want to implement mutagen. It was most complicated faction skill - that looks much harder to implement even than Cynwall concentration.
