No, Timber wolf is pretty darn strong, give or take some depending on the version. The Reboot one was able to go hand to hand with Wildfire and take some energy blasts from him for example.
I'd give it to current Donna, maybe 7/10, but pre-resurrection Donna would have a lot of trouble with him.
Timberwolf during PC days could take blows from PC Superboy, had a healing factor, and sharp claws. Plus agility and speed. Zero Hour TW was pretty nasty as well.
