Re-watching various Trek series recently, I can't help noticing now how odd it is that the ship's therapist for the Enterprise-D is always there on the bridge with her own seat, always privy to top-level info, always there in the heat of the battle (unless the plot needs her to be elsewhere). DS9 had at least 1 therapist, but he's never hanging around Ops (or seemingly anywhere else really). Neelix was at least considered the morale officer aboard Voyager, but he was rarely on the bridge at all. Of all ships, you would think that Voyager would want to have a trained counselor around (or have a person get trained to be one) to help the crew deal with the emotional stress of being separated from loved ones, being stranded, helping Maquis & SF to get along, etc. They probably could've come up with an ECH (Emergency Counselor Hologram) if they really wanted to. I guess in re-watching TNG, it seems odd that of all people, the therapist would get that spot next to the captain. I like Troi, but it just seems like a strange setup. A captain receives counsel, of course, but that's from the officers he/she needs it from. Janeway did alright without Neelix next to her all the time, Sisko and everybody else did alright, too. If it was just for Troi's empathic abilities, maybe that would count for an explanation, but it would be a shallow one. Troi seemed to be an exception in several ways, and it would be nice if she wasn't just being used for her Betazoid side, but perhaps that's what it comes down to.
