Clarification on Gem Description on the new Archmage Support in 3.24

Hey there,

in the patch notes it says

"

It also now has "Supported Skills have added Mana Cost equal to 5% of Unreserved Mana"

However in the 20/20 gem preview it says

"

Supported Skills have added Mana Cost equal to 5% of Unreserved Maximum Mana

Which one is correct?

Neither my email, nor my tweet or this forum post got a reply until now, but it was "silently" (this sounds so judgemental, but I don't mean it like that LOL) updated on the patch notes like an hour ago!

(I checked like every 90min or so)

Just wanted to reply to my post here, so other ppl can see it.
Would have loved to see no "Maximum" there, but shouldn't be too bad either way. :)
