Monk - Manta of Destruction - Flicker Strike

Not sure if this is intended, but...

A single use of Flicker Strike adds a single combo to Manta of Destruction.

Which says "Teleport to an enemy and Strike them" which seems as intended with "Build Combo by successfully Striking Enemies with other skills."

Now when you "Teleports and Strikes 2 additional times per Power Charge"

"Build Combo by successfully STRIKING enemies with other skills" seems like it should add 2 combo points per additional power charge.

This is not the case. Meaning Mantra of Destruction is not adding Combo for additional uses of Flicker Strike. Which seems like by design it should. So you can use Manta of Destruction outside each Flicker use (as long as you had enough Power Charges to get 10 combo for manta)

Just want to make sure this isn't a bug as I would love to be able to use Manta out of every 5 combo points Flicker Strike.

To further question this design, whirling assault does in fact add a counter for each strike (or hit) for mantra of destruction.
