Why isn't there a ground pound masterwork?

Every weapon glyph in the game, including whirling blades and spinning attack, has a +damage masterwork, except for ground pound, which has no masterwork of any kind. Is this intentional, and if so, why?

 

I barked up this tree a LONG time ago, never did get a response. Hope you get one.

 

Because they have not made bludgeon very powerful. I hope they do.

 

I love ground pound. I still use it all the time but it is pretty weak even at a higher level.

 

I think it's a good skill, but it's pretty situational. It helps a lot in some places that have super tough mob swarms, and it's decent to keep in a locked spot for occasional efficient damage/damage prevention when enough mobs are around you to make it worth it.

That being said, there's nothing about it that makes it especially powerful compared to other skills. Rend, thrust, puncture, skewer, knockdown, and crushing blow are all super good skills that aren't very situational and have +damage masterworks just like everything else.

It just seems like a totally random oversight.
