We reached Driftwoods yesterday on tactician. Perhaps we don't have optimal level, gear and builds but one hit is enough to deplete the whole armor and some health. Needless to say we have to do whatever we can to avoid getting hit,including perma cc, oil, ice, stun, petrify and every trick we can think about to keep them at bay. An archer can go up to 200+ crit in one hit. It took three attacks in one turn from an archer to kill one of our casters, hardest and longest fight we ever had in the game so far but luckily we managed somehow. I can see Source skills and death-preventing spells and cheese tactics abuse and if this keeps up :)
