Final quest battle against Archaon easier than the first fight

So I just watched the recording of Enticity's stream from today where he went up against Archaon, and in the final quest battle against Archaon, the enemy forces did not get the ward save bonus that Archaon's initial army had on the campaign map, making this battle even easier.

I don't think this is how it was intended so the ward save bonus should probably be enabled for the quest battle too.
