So, my gaming group just started playing DH, and we are two sessions in. We have a total of 6 characters, and are all still Level 2 characters. We have starting gear, with a few upgrades (most everyone has a flak vest, we have about 3 flak grenades, but mostly we have pistols, lasguns, autoguns, with mostly standard ammo).
With that in mind, my dilemma relates to trying to figure out if the risk/reward ratio that our GM is using is appropriate, or needs a gentle prod to be "rebalanced"
In our second adventure, we played for a total of 7 hours. The first 2 hours or so were spent trying to get information from an Adeptus Terra Adept, a Commisar, and a AdMech Magos, all of whom were unhappy with the others. We ended up getting the info we needed, and ended up in an active war zone. We had to fight through about 15 generic heretic scum with autoguns, and a sandbagged heavy stubber. We took some damage, but noone was into critical yet. We then had to storm a building with 4 more cultists (who all died from a flamer stuck through a window) and then 4 mutants, each with about 17 wounds. At this point, my Guardsman was into critical damage, and our assassin was 1 point away. We finally broke into the datacrypt we were after, only to happen upon the demon with a toughness bonus of 10. Half the party went into shock, and it was only amazing dice rolls from a 9 round hit with the an autogun and 2 handcannon shots with damage rolls of 10(from the adept, no less!) that put the thing down.
After 7 hours, 3 characters in critical damage range, and several corruption and insanity points later, we each got about 300xp.
As this system doesn't have a "threat rating" system, or "monster levels", its hard to really get an idea how balanced this scenario was. Certainly, the group was very close to losing multiple characters, and the non-wounded characters all accrued insanity or corruption, and were shocked enough to be mostly combat ineffective. I like a good, tight challenge, but this felt like the risk:reward ratio was too weighted to risk.
Thoughts from the community? Should I gently say something (notably, this is a friend with a PhD whom I have been playing games with for 19 years), or is this a relatively balanced thing that my group is just not used to yet for this rules system?
Thanks in advance!
