I'm actually ok with the wolves. The step noise is a known bug, in previous versions of the beta their step sounds were working just fine and you could hear them coming. Also, wolves are natural hunters, if you think about real wolves they know how to hide their presence and not make sounds when hunting their pray. But again, it's a bug, they do make noise or are intended to make noises.
As for movement, aggressiveness, damage, behavior, AI I think they are working just fine, could even be buffed.
If they are too easy it'd be pointless and the wolves are one of the key features of the game (even in the name), with that said I'd expect players to die for the wolves constantly.
I'm used to playing games that you need high surround awareness (like Escape From Tarkov) so for me I could say they are very easy to avoid and kill. If I'd give any feedback I'd actually ask for them to be buffed like I said earlier lol.
