Getting potential from fusing rate lowered?

I think the rates were higher as sort of an event for professions.

The only active events I see in that update note are these;

Profession Boom Up Event - 07.11.2011 - 08.09.2011
* 2x chance to earn an item of your harvesting profession rank or higher while harvesting.
* 10x chance to earn an item of your crafting profession rank or higher while crafting.

That should still be going on.
