This past weekend we play through An Eye for an Eye. It was very fun and the scenario is very good I have to say. I find it has a good balance between investigation and combat and I specially like the fact that a good investigation rewards the players with an easier final combat encounter.

In the first combat encounter, the Troll Slayer was knocked unconscious while fighting two Gors and he also lost his shield hand. Later one, the scout of the group was put to sleep by a single Reckless Cleave the Wargor (he was equipped with a two-handed weapon).
