Warrior Rune of Fury? "Adrenal Charges Longer"

Can someone please explain to me what this rune does and how it benefits a Warrior. Thanks.

It means that your adrenal charges fade slower once combat ends

So normally it fades after 25 seconds of non battle. Minor is 30, Major 35, Superior 40? Is that right?

not sure of the actual time limts but basically yes

anyone?

Has anyone seen one in game yet? I havent found one nor have I seen one being sold in the trade channel.

I don't think it's a rune, but a weapon upgrade. I found a Furious axe haft.

It says its a rune people just havent found yet I guess.

It's probably dropped from the final release, either that or its some obscenely rare item in the game, and knowing A-net's stance, there shouldn't be such an item. I'm guessing its not in the game at all.

Its listed in this webs knowledge base under "Rune Listing". Hopefully it wasnt something in beta that got removed.

Fury runes have been removed before release.
They no longer drop and old runes have been wiped out.
