Go to options --> Game --> Change ctrl keys
Scroll down to where you see "Change skill set skill (down)" and change to Shift + C. Assign "Change skill set skill (up)" to Shift + V
Now scroll all the way down to where you see "Control type B" and assign that to "X" key. Assign "Control type A" to "Z" key.
There it should be working like before. Once they actually do fix this then set to default =).
