This.
Kari is useless, all she does is mug at the camera and hope her looks distract everyone from the fact she's crap. Scottie was hot and she could build stuff....dumbest idea ever to get rid of her!
Did they get rid of her? I'd heard she just didn't want the fame that Mythbusters gave her?
Either way, Kari uses a gun and it's like "OMG I can shoot things lolz". Pretty much she's reduced to "I can paint things and make 'em look pretty!"
I liked Jesse as she reminded me of Kari, she actually *DID* stuff. She was a bit annoying, but at least I felt she was helping out. As it is how I see it:
Kari = useless
Tori = Doesn't do much other than lift things, weld the odd thing and hurt hijmself
Grant = Makes everything complicated, and also somehow manages to do everything else.
Jamie and Adam are often the only two I bother to really watch now, Jamie particularly entertains me.
