In theory, it's just an exchange of troops, because you have about 100 neutral units against you, and you have roughly the same number. Haven, Order, and Might have fewer losses, but that doesn't really matter, because you're just using level 1 units as cannon fodder anyway. Except in rare cases. For example, on Tron, it's better to save archers, even if they're just orcs.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
