Yes go test it. Go do 10 level 1 maps in Tram and 10 level 1 maps in Fel and tell me how much of a statisically significant difference you can see.... I'll be waiting.
I have tested or I wouldn't be opening my mouth....
I've been Treasure Hunting HEAVILY for the past 3-4 days ( Level 6s & 7s).
Out of the approximately 25 Trammel Facet maps where I was keeping track I pulled in 3-4 low grade legendary Artifacts.
Of the 40 or so Felucca Maps Level 6s and 7s I've pulled on the range of 25+ Legendary Artifacts.
Between this post, and my last post 10 minutes ago I pulled out 2 Legendary Artifacts out of a Level 6 Map in Felucca.
This isn't RNG. Trammel facet maps the norm is to go 10,15, or even 20 level 6 Maps before getting a Legendary.
Go visit Treasure Hunters Forum or talk to other hardcare THunters.
There is a reason why I quit Treasure Hunting since VvV, because the loot is absolute garbage on the Trammel Facets which is where I treasure hunt 95%of the time because I prefer those spawns.
Out of boredom I started doing some maps, and started in Felucca and starting pulling in nice artifacts. As soon as I started doing Trammel Facet I pulling the same junk and I told myself this is the exact reason I quit treasure hunting in the first place.
Just looking at the items dropping you can see a difference in the intensity from the Trammel Facet.
You can lead a horse to water but you can't make it drink.
I'm just giving a heads up to people out there who are banging their head against the wall in Trammel trying to get Legendaries. It's a landslide for Felucca in terms of pulling Legendary Artifacts out of Treasure Maps.
