My monk has an 8 in intelligence and 10 in strength. And she definitely doesn't need a protector.
If you're playing a monk, you care about dexterity, wisdom, and constitution, in that order. The rest don't matter.
Getting back to the OP, I think lycanthropes should be specifically resistant to damage from anything but silvered weapons, and you should need a silvered weapon (or maybe the magical equivalent) to finish them off, just like you need fire or acid for a troll. It's such a part of the iconic lore that it feels weird that they are now just another mundane creature, for the most part.
I also hate that most creatures have lost their immunity to non-magical weapons; I would have gone the other way: keep the immunity to non-magical, and buff it to include resistance to magical.
