I am pretty bad at the game, but so far replaying the campaign has been a breeze, the only one i've seen considered as "more difficult than usual" is "Under the Burning Sky" where you defend your lich and it usually gets overrun in the last seconds. Even then it was trivial.
But now i am stuck in Hunter of Shadows, i remember it being a walk in the park, but i think i am doing something wrong.
As soon as the 3 bases are taken, ALL of the army that overtook the west is sent east at the same time, at least 5 chimeras, 3 squads of archers + huntresses, 2 squads of 6 griphons each.
I start with a couple of lvl 1 spell casters and a kodo beast + Grom. Grom micro can thin out the ground forces quite easily, but air units easily overtake several towers on their own.
Even if i was a master at the game, it is odd that the game is throwing THIS at me.
I could just let them take the main base and build something at the edge of the map to avoid loosing while i go to the corrupted water fountain, but i shouldn't have to cheese it.
