What Primal Slayer said, it's more so about keeping it consistent that's the issue with her.
Writers in the DC Universe seem to forget she's a demi-godess herself. If you remind people of that, it makes a lot more sense how she can be a threat to WW.
A rundown of her powers are:
Super speed: has been stated to be close to, if not as fast as The Flash. Can easily speed around WW herself and tag her.
Claws: Can cut through almost anything (think Wolverine's claws), including Kryptonian skin.
Strength: Can knock around and wrestle sturdy heroes like WW.
Durability: Can take hits from WW and Kryptonians.
Combat: (This ones kind of weird with her because she's not like, proficient in a martial art like most people think when you mention combat as a feat) she's able to fight and out maneuver WW, who's considered the best combat fighter (bare handed or with a weapon)in the DCU.
But I always though a cool ability to add would be if her claws could cut through magic as well.
