Which character dodd you miss the most after they died?

I miss Tara the most. Then Joyce. And lastly Jenny. I miss them all terribly. But-as I said-I miss Tara the most.

I really missed Oz.
Ok, I know that he didn't die, but he died for the show after season 4's "New Moon Rising" ep.
He was such a cool guy!
Moreover, I really liked his feelings towards Willow and the scoobies as a whole.

definatley tara, she and willow were perfect for eachother, i cried so hard wen i saw her die

This may sound weird, since she ws only in a couple of episodes, but for me it is probably Kendra. I liked her and felt like there was so much more that they could have done with her. Also, I know alot of people liked Faith, but I never really cared for her, so I would have preferred if they kept Kendra.
I also really missed Tara, but I am not sure how much there would have been for her to do if she had lived until season 7, since there was already alot going on.
Finally, I also missed Jenny Calender. I liked her and would have liked to have seen more progression in her relationship with Giles.

Oz-I know he didn't die, but he was my favorite character on the show. I did like they brought him back in S8 though.
Tara-The way it happened was heart-breaking, not to mention what happened after it.
Spike-I know he came back on Angel & Buffy S8, but when he died on Buffy, I really teared up.

If you count the comics too: (Spoilers if you haven't read them yet)
Giles-Why did he have to die anyway? And furthermore, it ruined any chance of redemption Angel had for the gang, that Sucked! I hope Joss brings him back.

TARA !!! she was just so beautiful and sweet and cute and nice and......the list goes on!
I thought that in season 7 when she was gone ther was definetly something missing

Tara and Anya

Cordelia... sh was a bitch in the begining, but after she became poor she got more down to earth..

CORDELIA and ANYA and DARLA because they are the best ever i cried when each of them died .

Spike's death felt the most heartbreaking to me, especially considering that he was my favourite character (tied with Buffy) and the way he died, sacrificing his life for the world and the woman whom he didn't even believed that loved him back, seemed very tragic, although I know he came back on ATS and I didn't get to actually "miss" him because of that.

When it comes to a character that I missed, it will always be Doyle (there wasn't a single episode that I wouldn't miss him) but he isn't from BTVS so I don't think it counts.
