Question about Double Mastery (Dilligence)

I just finished reading the topic here in Q&A, I was just about to necro the topic, but, I decided to make a new topic.

The thread didn't answer the questions I had in mind.

Will the 20% double mastery also affect our alchemy fusing results?
Meaning will we be getting more "Cool" results rather than "Good"? ("Cool" gives hidden potential on equips)

It just doubles the experience given from professions.

aw , i was hoping it would do more than just double x.x

Adding to what Locked said, Double Mastery only applies to a secondary profession (Alchemy, Smithing); harvesting/mining exp does not double.

Edit: Whoops. Totally forgot about crafting oils/plates/jewels. That can be doubled as well.

It's quite useful if you decide to switch professions. You'll get it leveled 20% faster if mastered.

or... you know... leveling smithing/herbalism up over 60 times to max the WP and HP bonus ._. does help a LOT.

That too, yeah. Because dilligence is no longer that useful by then :p

Yeah, I know guys.

I was hoping it would help getting more "Cool" fusing on Alchemy.
Since my return in April (from 9 months), I'm very far behind in terms of equipment.

And, those extra %stats does help.

I guess I'll get a few other characters to 30 & mine for supply.
