And who do you choose in Haven, Archangels or Seraphs? I can't decide for sure yet. I haven't figured out what Seraphs cast. (Maybe someone can tell me?) I can definitely say that Archangels are more reliable; they won't deal ridiculous damage, and debuffs don't affect them. But Seraphs are a debatable choice. If you have access to light magic, the "Divine Power" spell, and the enemy hero doesn't specialize in Dark magic, then there's no need to think twice. Definitely choose Seraphs.

Of course, this is just my opinion.
