I have a number of my recruits constantly crossing the happiness 100 line. It's really annoying. I think that the happiness drain value should change at 75/125/175 not 50/100/150. And that you should give some really awesome bonuses for happiness 200. Probably double bonuses to all clan skills, like transmutation, enchanting and diplomacy.
But in general, I like the idea of making it harder to pin people at happiness 200. It was too easy. This is not to say that it isn't too hard now. I have not played enough with clan members under the last few patches to have an opinion.
