I'm not testing but I'm also in the "I like challenge" group. If you're planning on reducing the difficulty even more, I suggest (if possible) having 2 different difficulty levels, one for those who play for challenge and one for those who play for 'the story'And Beta 3 is out to testers. Skavenhorde should be pleased to know that I didn't do much to nerf the difficulty overall - just in the more annoying spots. And there are new rogue abilities for Dirk.
Oh, and those really cool explosives the party can have made for them? The hobgoblins have them now, too. And know how to use 'em.
