Group inactivity is worst, but sometimes being illiterate, for example, in literate pack can be worse.
Yet many people have their own view for realistic. For me, it's realistic when you mostly use body language (but describe it clearly and what it means so players can understand), when your pack has realistic ranks (many put hunters and healers, but only ranks are dominance, wolves don't have jobs as much as I know) and when you are realistic (tiny wolves with sharp ears and neon colors aren't really seen in wild).
So yeah, it's hard to find realistic and literate groups, but keep trying. And "rubbing salad in their wounds" made my day.
