I'm DMing a pathfinder campaign and it's been going pretty well. The Barbarian is having a grand time cleaving hordes of weak enemies, the Cleric is doing fantastic in the undead segments, and the Sorcerer is a great source of overall damage potential against bigger enemies.
However, one of my players is playing as a Rogue and can't seem to find his niche in the party. He is always leading the way in dungeons, so he can check for traps, listen for enemies, or scout ahead in stealth.
Unfortunately, a lot of the time this means he gets too far away from his party, and more often than not is the first person the enemies see. He has the lowest AC and health out of any other party members, yet he is always the first to enter a room full of bad guys with weapons pointed toward the door.
As a result, he has come within an inch of death multiple times, and spends large portions of many encounters unconscious and not getting to do much. Worse yet, he has gotten so frustrated with his character he barely even seems to be trying anymore, so it happens more and more frequently.
I'm now conflicted between letting him die, which I am certain will only alienate him further, or finding some other way to accommodate his play style. Would it be best to just have him re-roll as a fighter?
