Provisioning Hirelings

Wolfsspinne

I just looked through my mail box on the live server. And I found, just as every time I do this, some very old letters with unopened boxes from hirelings. You know those boxes that contained random ingredients that where leveled to the character who opened the.
(The boxes that were replaced because you could have sent to a low level character and then open with a high level crafter. Before those boxes were removed I had multiple characters with just enough skill to receive such boxes.)

It was than when it occurred to me that with the new tierless ingredients the old trick could work again because now all characters regardless of their skill level would get the same ingredients.

So did anyone check this out?
Do you get the same yield with a Lv28 provisioner as you get with a Lv50 provisioner?
