I'm going to turn the Sylvan faction into a menagerie, but not like in the fourth game; it will rather be a swamp like in the third.
And I've decided against the Stronghold because of its racial ability – Blood Rage, it's too similar to religious fanaticism. There's a historical incident where crusader knights were besieged in a captured city, and things were going badly until a monk dug up the spear that was used to pierce Jesus. Overjoyed, the crusaders left the city and defeated the Arabs in the field...
Your Stronghold is excellent! Especially the Asp.
