I had to get several CC items like feet, a tail with several coloring options, legs and walking style to even begin to think of those furry sims with a big dog mask as werewolfs. But we cant make them immune to negative effects at all and that is just bad design. I couldnt even find any way to trigger toddlers to howl but they and children are constantly enraged by teeth. The balance is abit off here.
Im looking at my apex werewolf right now. Its raining, he is playing the the rain, having a good time... while "hates being wet" is active.
I play with vampires since the pack came out and werewolfs use a similar, practically identical system. Except the negative effects. My vampires are a delight to play with but werewolfs are so difficult and require constant attention. They are almost as bad as babies and those are just objects where we have to guess their needs.
These things require a serious overhaul.
