I'm new to the game and just have the Core Set , The Hobbit: Over Hill and Under Hill , and The Hobbit: On the Doorstep . I solo played through the "easy" scenario in the core set a number of times until I beat it and then moved on to the first scenario in Over Hill and Under Hill .
I tried using a single deck as I'm playing solo so I went with the recommended "Leadership and Spirit" deck. I got pummelled very badly by the three trolls on my first few attempts. It appeared that I'd rushed through the first scenario quest card too quickly and wasn't ready for the trolls that pop up on the 2nd quest card so on my last play attempt, I held back and built up what I thought was a good force of Bilbo, Nori, Thorin, and Gloin as well as Fili and Kili, a Longbeard orc slayer, 3 snowbourn scouts, and a Silverlode archer.
What I found is that if I'm reading the troll cards correctly, it's mathematically impossible for me to beat a single troll before the threat count reaches 50. The Troll trait on one of the cards says that only a single character can attack a troll at any given time. The only character that can possibly do any damage is Thorin with his attack of 3 vs the troll's defence of 2. So he can only do 1HP of damage per turn and the weakest of the trolls has 10HP. Within a few turns, the threat count will be high enough that all three trolls are engaging every turn and using 4 sack cards. Thorin is always one of the first to get tossed into the sack and it then becomes impossible to harm any of the trolls. One can hope to pull a bunch of Gandalf cards but even he can only do 2HP of damage per turn so it's still not possible to take out a single troll before everyone's dead or the threat reaches 50
Is my take on this correct? Is it simply not possible to beat the game with the recommended deck?
I tried to play using both of the recommended decks but found that it's not possible to construct both decks simultaneously as both decks require 3 Burglar Baggins cards and only 3 come with the expansion.
