the character's personality was just so... random. There were like three different versions of her and none of them merged together well. The aloof smart person who can figure out anything, the party girl who gets drunk and plays tongo with Quark, and the avenging valkyrie who fights with and hangs out with Klingons.
People in real life have multiple ways of acting in different situations, why can't a fictional person do the same? Jadzia Dax was a smarty-pants party girl who enjoyed hanging out with Klingons. Seems about right.
