I like to make interesting little twists and turns as well; I've never played someone with "battle fatigue", or "shell shock",  which is what I'm guessing they would call it in D&D's world (lacking more modern terms like PTSD), but given Leofwine's backstory, I thought it would be an interesting flaw to saddle him with.  He's still fairly well functioning, if slightly paranoid, but will likely have his moments (and will probably become rather uncharacteristic if they ever go up against goblins again).<br/><br/>As for party leadership, I'd imagine Leofwine would just go off the assumption he's leading, because as the leader of the militia, he's just gotten used to taking charge. It also fits his alignment role. But we'll see what happens IC.
