Being in the same game with
@kenada, I can say that it's much more interesting when XP triggers conflict—as in, you can't reasonably max out your XP in a session. To pursue your playbook triggers might ruin the score (which is a crew rather than character XP trigger, but still an XP trigger). Expressing your character's beliefs might conflict with struggling with vices (a stretch to be sure, but I've seen it happen). And conflict as such isn't even necessary; sometimes a given XP trigger just doesn't come up, or it would feel very forced to try to bring it up. In the very session
@kenada mentions, things just kind of barreled along and I didn't get to bring up my character's vice or traumas, even though I'd had an idea for how that would likely happen before we started. But we had a surprise twist that changed the whole dynamic of the situation.
One more thing: While it does feel great to max out your possible XP—when you manage it too often, it starts to feel like a cakewalk. I've had a couple stretches like that and might even up my standards for what counts as meeting a given trigger condition!
