Tactician Suppressing Fire + Combat Frenzy + Artillery Ballista

Hi, im trying to use Combat Frenzy in my Tactician and I get Frenzy Charges perfectly when my Suppressing Fire pins anybody.

The problem is my Artillery Ballista also pins thanks to Suppressing Fire and with Combat Frenzy activated, the Frenzy Charge for the pinning go to the totems instead of me, not as the gem states that "when you pin".

Obviously the totems are pinning and Combat Frenzy works correctly granting them Frenzy Charges but, is this intended? My own totems steal Frenzy Charges from me! And even they cannot use Frenzy Charges. I tried to allocate Tumult and Ferocity, but they cannot support Artillery Ballista so I assume that Frenzy Charges they gain should be transfered to me.
