I loved sea of flames in my ardent flame. It didn't cost anything to use and the fireball stayed around until I used fast travle, died, or turned itnoff myself. I loved it. It was one of my favorite moves to use. I even named the fireball. It was willow. I get on this morning try to fire up willow and I get this stupid ball of light that is NOT willow. And so I find out it has been changed to cauterize which heals. I have other healing moves. I don't need this to heal and flames of oblivion isn't as good as sea of flames was.
