Poe 2 discipline aura bot working as intended?

In path of exile 2 the discipline aura says it converts 38% of the sources maximum mana to energy shield for allies but it doesn't seem to work that way. It scales with aura effect but even on my character with 8400 mana and no aura effect it still only gives 300 energy shield. If it was based on flat added mana pre- percentage it might make sense but it doesn't specify that. Is it just a wording issue, a lack of understanding or is it not working as intended?

It looks like you are reffering to the pre-launch version of Discipline that was teased in late November. At level 19 it had Allies add 38% of your Maximum Mana to their Total Maximum Energy Shield Mechanically that's very different from conversion, just saying.

But since EA launch the wording has been Grants Allies +309 to their Total Maximum Energy Shield (also level 19). So it's not depending on mana at all.
