When my PC was surrounded, the DM said the outriders “had the drop on me”.I disagree. If the PCs can't die, IMO, what is the point of combat? Save a lot of dice rolling, and just announce a victory, hand out the loot, and move on.
It feels like a 'participation trophy' sort of thing. If the PCs can't die, what success can they claim? This is not a rhetorical question.
I'm not saying it is wrong, I'm pointing out that I don't understand.
When I surrendered, the DM told the group to note that particular phrase meant a PC would be considered helpless in that situation, and could be killed at will. IOW, had I not surrendered, that PC would have died.
