From the patch notes:

⦁ Enhanced Burst Now also adds a 25% chance for hitting with a Burst ability to award 1/2 combo points.

I am not seeing this on Prime. I beat the poopy out of a dummy for 5 minutes and never saw more than one combo point at a time, and I main a Paragon so I know what I am looking for.

In the tree is mentions nothing about these combo points so was it not implemented?
