Her ult is fine and it gives her some presence in a team fight, even if she dies, so I have no issue with it remaining how it is. She has a lot of things going on right now, and I feel like her ult is at the bottom of the list in terms of adjustments. If her shield and Q2 damage gets modified, and possibly her E range, this will be enough to pull her down a bit, and nerfing the ult may put her in an overly weak state.
All things considered, Camille isn't terribly OP at the moment, unlike some launch champs in the past coughCertainlyTcough, and only a few nerfs will put her in line. The boards, though, seem very intent on a full blown witch hunt and execution.
