Warders of Men's buildings should be the only ones for werewolves to not require low development, meaning they can benefit from them anywhere, plus the usual benefits of development (levies, taxes). But we had conflicting reports that this part might not work well right now, so you might have to wait for an hotfix handling this issue.
In any case, the Warders are in a difficult position at the start, so it's much easier to learn the ropes of werewolves play with their easy starting character, Yuri Tvarivich of the Silver Fangs.
