no you are the pathetic one, sinding was able to control his lycanthropy even after you get the ring of hircine.
Sinding is a Daggerfall style Lycanthrope. Instead of just making assumptions and trying to make a point, read carefully what I had to write. Normal werewolves can transform TWICE a day at will, but they still suffer from forced transformations.
Replay the quest or rewatch the youtube videos.
"That is why I wanted the ring. It was said to give men like me control. I am sure you heard of men who shift to beasts under the influences of the moons. I am one of them. A werewolf."-SInding.Sorry bub, lore is still lore and you simply lost in this argument. It is what it is friend. If you don't like it, then you can take it up with half the lore masters here in the forums, or at least someone who uses common sense. Sinding wanted the ring to control his Lycanthropy, but Hircine threw a curse on it because he stole it.
