I like Jadzia, too. She's strong, beautiful, good humored, smart, and warm-hearted. I love Sisko calling her "old man." The depth of their friendship really came through.
I wish they didn't kill her character. They didn't have to. She's a Starfleet officer and could have just been transfered off the station to another posting. That happens to people in armed forces all the time. While I do like Ezri, I like Jadzia more.
