does grouping increase loot values to better odds like wildstar?

I have been getting better drop rates from bookshelves when grouped and it feels like its not a coincidence.
Anyone have the answer for me?

Not that I'm aware of, should be equivalent drop rates, solo or grouped. Just a coincidence most likely. At the very least, I haven't noticed this in my pts experience.

Hope this Helped,
