I think she is totally underrated as she worked very well back in Tekken 2, even moreso in Tag. As with our main man, she was harder to use but excellent in the hands of an expert.
Shit, I remember when I could use just about everyone in Tag's roster.... even to the point to where I could randomly select Mokujin and own.
I really hope Namco decides to release some type of Tag mode for 6. Wishful thinking for sure, but imagine the possibilities!! I think it could be done with digital downloads/add-ons.
