Re: Should K'Ehleyr have replaced Troi?
I would think she needs some sort of training to be a counselor. To my knowledge K'Ehleyr has no background in psychotherapy. As for advising the captain, he has no shortage of those. Though one skilled in diplomacy would be a plus. Wasn't Troi on the bridge because she was an empath and Picard figured that would be useful? A Captain's prerogative type thing?
Though as an Ambassor K'Ehleyr could overrule and second guess Picard in certain situations. I can't see any Captain wanting that. I'd require her to resign her postion as an Ambassor and join Starfleet first.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
