Wizkid, I'm surprised that you think that. One of the things I loved about Orion's Hounds was what strength Troi had - Christopher even compared that strength to others in the crew with similar abilities. Plus, it was Troi's brand of strength - of compassion and understanding, rather than big guns and aggression - that ended up being what was needed to save the day. I went into Orion's Hounds having read some complaints about how Troi was handled as 'screaming and yelling from emotional headaches', and was feeling some trepidation in that regard, but I ended up being floored with how awesome she was. I'm trying to think through it... I'm not sure if all the moments that had me muttering 'yes!' and pumping my fist in the air were Troi moments, but some of them definitely were.
I think how 'out there' you think she is depends on your own perspectives. Another reason I loved Orion's Hounds as much as I did was because of how close in spirit I felt to Troi. I may not have psionic, empathic abilities, but I'm very affected by the emotions of people around me, and have similar moral values to how Troi is portrayed in this book. I found it hugely encouraging watching her using her abilities to gain a greater understanding of the people and creatures around her, and seeing her successfully trying to promote forgiveness and compassion and non-violent solutions.
Compared to Troi, I find most of the other characters much more 'Out There', whether it's Geordi with his implants and crazy engineering skills; Picard as a leader of a gigantic ship; Worf from a completely alien warrior culture; Data, the robot with no emotions; or Dr. Crusher, the Miracle Healer... When I think about it, Troi, the empathic counselor (at least as Christopher portrays her in OH) is really the closest to me in most ways.
