A strong independent character turned into Worf's personal cheerleader. Glad the Ezri thing with Worf didn't last long, at least the producers had the dignity to leave that be. Oh, they decided to have her shack up with Bashir gah! Romantic relationships within the crew had to be the thing in the War seasons.
I did love Jadzia, and even Ezri's scenes with Sisko, the bond was always there, although I believe Dax' absence from season 7 would've been interesting than replacing her. I mean DS9 was cluttered with immaterial characters--since it's a war I thought more character should've been lost.
Honestly, Quark should have gotten one of the Daxes. Probably Jadzia. I thought they had good chemistry together, and Quark could have shown immense character growth having to deal with a woman in a relationship as a social equal.
