As of now I'm finding most trash mobs a slog with a 4 character party because even at level 4 only my fighter is capable of consistently taking out a 10hp goblin with less than 2 hits. I'd say I'm dealing with a character getting downed in about 60% of combats and that makes things feel even worse because now I have to scramble to help them, hope they can heal before gettign downed again and then going back to attacking. Without changing anything else about the difficulty, a fifth party member would bring the experience down to being manageable, with trash mobs actually being trash mobs because as it stands my experience of a "trash mob" in this game has a decent chance of being a TPK if I'm not really stretching my strategic muscles. And a boss combat in this game? At this point I'm taking it as a given that I'll definitely die at least once.
