Don't worry, they do not nerf a character based on tournament results.
There are many things wrong with Ivy. Also, it's not about taking out iCS, but making balancing it better.
A couple of things that I can think of (which I am sure that you have already thought of, or have apparently already been addressed):
3B should always launch high enough to get the 6B8 combo.
6[B ] should be altered in some way to be more useful.
A damage increase (I think a 15-25% increase is reasonable?)
Change 8A+B so that it has the same properties as SCIV so that we can use it as a combo finisher.
In general change the fact that she needs to get lucky with a counter hit to do some good damage.
