So as the title says I'm very new to the game. I have one copy of the core set, the Black Riders, and A Journey to Rhosgobel. My friend and I beat the first quest fairly easily despite having to teach the rules to the other player (and the mistakes he made due to misunderstanding certain rules).
Then the Hill Troll in the second scenario completely ran us over. We were having a lot of trouble questing successfully (first game we immediately ran into that Orc that gets resources tokens to boost his combat) but even in the second game we just couldn't deal with that troll. I was playing a Tactics deck, the other deck was Lore. We held the troll back for a while with that Lore card that stops an enemy from attacking but between trying to kill the troll through his 3 defence and keeping questing enough to keep our threat from climbing we struggled to deal with the enemies that were coming from the encounter deck.
My current thought is that the Lore deck may not have enough teeth for what we're trying to do. As it stood, I had to kill the troll and most other enemies because Legolas and Gimli were the only big hitters we had (I had to use Landroval for questing).
Can I get some general advice on deckbuilding and trollslaying in particular?
