"In honor of our fathers" - "One Khan, One Clan" [Campaign 3, Mission 2]

I didn't notice any particular passivity in this battle. Starting from week 6, armies came regularly, "with no chance" of winning. Cyclops threw goblins if they were standing nearby, but they weren't deliberately positioned to do so if they were scared away. So, a lot of time is spent on speed-ups/slow-downs, because the enemy shamans recast them.

Well, if it really is like that for the hero in the Horde faction, then that's good.
But aren't the shamans faster at casting Earth Daughters? The Earth Daughters also have higher initiative.

[Earth shamans can also debuff wyverns well, and the damage from lightning at the start (when it's most needed) is low.

I don't quite understand about the wyverns, how? Do they have a spell to increase attack?

And regarding the fast lightning, I'll give you a tip on how to use it quickly. Place the leader close to the Earth Daughters, then use them to attack the Earth Daughters so that they go faster, sacrifice a goblin to them, then use the leader to speed up the Earth Daughters again. With this procedure, you can manage to cast Chain Lightning even before the start of the second turn, because the leaders have good initiative and they often go first.
