Rage charging mechanic and Ballista Totems not working

I don't know if it's a bug or intended mechanic, but using Berserker ascendency Crave the Slaughter (rage generation) doesn't seem to be working on Ballista Totems in any shape or form. They don't generate it for themselves and it doesn't generate it for the caster. I switched to Shrapnel Ballista which is an Attack, to test if it's limited to Ballista Totem Support, but no. Same story.

Yet every bit of information I have, should tell that Totems generate charges and Attacks generate Rage.

If it is indeed working as intended, could Rage be revisited and changed? The ramp-up time is incredibly slow to begin with because apparently 1-attack (no matter how many projectiles) = 1 rage, with a cap of 3 rage per sec if you have 3.0 Actions per second?

On Toxic Rain it just ticks 1 Rage per second, based on targets hit i guess... Or spores count as individual attacks?

So the description that "Gain 1 Rage on Hit with Attacks" is very misleading.

Edit: Just to clarify, the Totems do get the benefit from the character's stats increasing. It just doesn't generate rage for the caster or themselves. Changed the title a little bit.
