John, I liked reading your comment. It has lots of interesting ideas for RP. Sadly, I don't think any of them are useful to the playerbase.
Overlooking the "RP better" base of your argument, which by this point has been beaten so far into the earth all its missing is a gravemarker, the things you suggest are simply suicidal. Why would I RP my PC being needlessly creepy when 1. The natural reaction on Zalanthas to most things is violence and 2. There's simply no reason to. 3. Nothing in the docs supports this?
You contradict yourself. If my PC is unmanifested thick skulled and superstitious, why then when they manifest would they be playing into those same superstitions now knowing a host, if not all of them, to be falsities? To take a real world example would be a person acting miserly for some reason because they married into Judaism.
The problem is ecsacerbated further because once the witches are playing the oppressed person the brunt of superstition is on the mundanes. This is problematic because, considering there's nothing religious about magick, there are no rites or rituals, hence nothing to be superstitious about.
Honestly, the desert elves work far better for a target of superstition. They have rites they perform coupled with weird beliefs, are often isolated and xenophobic, and there's the language and racial barrier.
If you want to see better superstition I suggest a petition to have the superstition page on the site expanded and also suggest that each spell, in the help info, have a suggested rite associated to it, because currently it's simply a cookbook and not the necronomicon.
