Hex in itself is a good status effect to be able to deal, but for it to be Red Velvets only SA is a bit poor. It basically means when Red Velvet deals hex neither her or the opponent has a signature ability; i.e. levels the playing field. SA’s are supposed to give you an advantage. Suggest that Hex itself is kept as a status effect, but Red Velvets SA should be to cast hex AND steal the opponents signature ability for Xseconds.
