I think it's pretty apparent warriors aren't particularly good. That wasn't the point. Surely there will be some form of re-balancing to make them more useful.
I do agree that source hunters should at least be somewhat trained for combat, so perhaps some lee-way can be made like that. My main problem still comes down to the following.
If you still insist on a nerf after all that, how can you reconcile the legionnaires surviving a moment in their two year struggle against undead and now orcs? It wouldn't make any sense. They were drunk but functional, not out of their minds.
And seven Legionnaires, presumably level 4 were sent out to find the lighthouse, and 10 more to escort the guy to the burial mounds. Even with sword damage, that would be more than enough to handle the encounters you find out there, but they all still died except for two anyway. What's your point?
I'll just respond to this because the rest is mostly about what people find fun in games. I like to feel like I get punished for metagaming excessively (I believe the idea that all encounters should be fair is in this category, and I frequently find when I DM D&D for my friends they find dungeons more fun when they need to figure out if they must run rarely, but still sometimes, from things they find).
Anyway, I think that's a strange problem with the narrative, then, isn't it? If they all keep dying when they do things, how the crap have they lasted two years? I didn't get super far into the game narrative, so I'm not an authority, hadn't even seen the lighthouse bit.
It seems to me that legionnaires surely couldn't be defending this place with that kind of record going for them, and something should be done about that. Fewer guards sent to these places having been underestimated or some such, with a good deal of other things gone well, etc.
Then again, I do like my realism in reasonable amounts. Eating and sleeping and hypothermia etc. I do still find to be overkill, noting, so I'm not one of the extremists.
