Personally, I found her character grating over time. I didn't understand her choosing Garak over her father after all he'd done and gave up for her. She just kept on betraying him the moment she felt a little angry then it was right back to him because she couldn't stay mad. I found her death useful for the BSOD and Despair Event Horizon that Dukat underwent but I felt it weird that Garak didn't have one as well. I understand that, being a spy, he would hide it but he didn't even bring it up when he was fighting The Dominion on Cardassia. It was like it was like she was here for a moment then gone. I thought the character was good in theory but not well executed by the writers.
Okay, good first post.
