Pre nerf Rockmolder???

Hi guys,
someone know if anet has modified the pre nerf rockmolder to 10%....????
I'm becoming crazy because i've 2 10% while before the holidays one was teh pre nerfed 20%

As part of the 13 of July 2006 update, Rockmolders were retroactively changed so that all of them now have 10% chance to halve skill recharge of spells.

x2

Everyone who had a 20% got screwed over =/

Yip; really old news. I had one in storage thinking it might be worth something a few campaigns later. Then it went off to the merchant.
