Personally, I would be more annoyed at the people who totally misinterpert Tifa's character just because of her chest size.

She's not very realistically porportioned, but she's a great character and I really do like her a lot. She's probably my favorite in VII, come to think of it.

Just try and ignore the shallow people who judge Tifa based solely on her apperance. When you get deeper, she's a very strong, interesting character.
