I sent in a bug report last night after noticing that my screen shakes after every time my lightning warrior uses her Charge feat (along with every time my shadow priest detonates all her DOT's at once, though the screen hadn't been shaking after that for many months!) The shaking screen quickly gives me a headache. I hadn't even realized that it hadn't been happening on my shadow priest until after this patch. Didn't miss the visual effect one bit!
Mine shakes every time the unstable spell (forgotten its name) kicks in on my shadow priest - I love that. Best thing ever when in big fights and everything explodes and the visuals really convey that.
