Unless no one stood out in particular (or, for that matter, exceptionally sucked) I tend to go: Roegadyn (regardless of job - yup, totally biased and don't care) > dps job > either tank or healer (depending who was better at their job OR if both equally good, the one that looks better). I always commend people, unless the party really, really, reaaally sucked and was ridden with bad attitude.
