Bloodfest does not require the agony of grinding at the Battle Arena so while it's not as good as Omnislash, I accept it gladly since it comes free.

Yuffie isn't a bad person, she's a thief in the vain of other fantasy thieves like IX's Tantalus or that dude from VI who insists he's just a treasure hunter. She never did any sort of real crime or supported any such crimes, either.

She's just in that angry, rebellious teen phase only it's tinged with things like her hometown being a caricature of its former self while the evil bastards who beat them rule the world. She's not out to hurt anyone except Shinra and she has much less blood on her hands while trying to do that than Barret or the rest of AVALANCHE do.

All she wants is to restore her great home to its true glory.

I can understand not liking Yuffie but she's so...incidental that I can't understand hating her with any kind of passion.
