"Supporting fire" Minion base damage is 1-4 at level 8?

I'll just assume this is a bug and not intended:

The "Supporting fire" unique minion from the Tactician ascendancy has a damage of 2-6 at level 8, according to my tooltip. This is on a character without any other "minion" modifiers (except the 20% from the small ascendancy node), 87 Str and 117 Dex. So in total, the skill should have roughly 50% increased damage already from the skill effect and the small node, meaning that the base damage is more likely to be around 1-4.

Additionaly, the skill benefits from "added damage" modifiers on quivers, adding them directly to the tooltip, which also shouldn't happen, since minions do not benefit from your equipment unless explicitly stated.

And the tooltip kind of checks out: Firing the skill on a "Rasp Scavenger" lvl 28 white mob in Deshar brings it down to around 50% of HP, if all 4 salvos hit (with the bonus damage from quiver, getting 6-15 dmg tooltip).

The Mercenary no longer has real access to ANY minion cluster and the skill (probably) doesn't level past 8 when you allocate it, meaning, that the skill now has to scale completely on its own (and maybe from gear), which it kind of can from the skill effect (1% dmg per 3 Str/1% acc per 3 Dex) but not if you start at 1-4 damage.

+1, same there

I may also be completely mistaken and the damage in the "Command" tab of the skill just applies to the 'flare' you are shooting (yourself?). Then the added attack damage would make sense but then why is there the "20% minion damage" modifier listed. Just confused at this point...
