I am playing Ailsa (in veteran mode/enemy scaling off) and following the Curse campaign I have arrived at "A Realm gone Mad" scénario, and there I found a challenge which surpass all my expectations: Multiple groups of Trolls with 4 chargers & 3 pups, compete with the raving "humans" locals to kill with ease my little group. Acting in concert 2 Troll chargers can kill any opposite numbers, and they regenerate... I completed this small campaign with the imperials which have a better armor, and can boost their dommages, but Ailsa doesn't have the time in this campaign to build much strength/specialties. For me this scenario look slightly unbalanced, but you may disagree... and I take any advice!

Well, for Ailsa it is a little harder admittedly at this junction - your best bet is to either summon defensively or give defensive spells to your front units and take a very cautious approach. If I remember correctly, the Trolls and HUmans will attack one another, so kiting them with a flying unit may also be a solution. Getting a spirit wolf or ancestors is also advisable, as they can attack from mountain hexes, which are not accessible to the enemy.
