LeMazing...it doesn't force your "overall CL" to a certain value.
What it really does is put a cap on the max that any particular equipped ring can have.
So...for example:
You have eight rings at CLs 8.3, 7.4, 7.0, 6.5, 6.0, 6.0, 5.4, and 5.2
You lower your ring cap to 6.2.
Your rings are now effectively at 6.2, 6.2, 6.2, 6.2, 6.0, 6.0, 5.4, and 5.2.
Your overall CL is calculated according to the EFFECTIVE CLs of your individual rings...so it might not be the same as what you set on your "down-level" widget.
Make sense?
