Myself and another GM just ran Chapter 1 at our local game store. My table bit the dust after getting spotted by a patrol (a failed Stealth check; player turned in a Hero Point and then rolled a Critical Failure. D'oh!). The gorumite warpriest kept 2-action healing the two veterans, which pretty much negated any damage the party did, and on the veterans turn they did their Heavy Swing first each time, scoring more than a couple crits. The party figured out "concentrating fire" and "kill the healer" too late. Game over.
The other table made it to Ordulf. After killing him three times, the table looked thoroughly dejected and were all ready to call it a game. I didn't stick around to see how it ended.
This module is no joke. Experienced players should have an easier time, but I wouldn't count on it.
