Loot Scaling: exemptions..

I'm curious as to what is actually exempt from loot scaling. Some say that Rare materials are.. Some say otherwise.. I know golds are exempt from it, but what else?

From the GW site:

Update - Friday April 20
Loot Changes

* Adjusted the following items so that they are now exempt from loot scaling:
o Skill Tomes
o Scrolls
o Dye
o Rare materials, such as Ectoplasm
o Gemstones from the Domain of Anguish
o All other rare (gold) items
o All unique (green) items
o Special event items

Beat me to it

I seem to get a lot crafting material (Not rare) When farming

I have noticed certain areas in the game drop more rare materials (example I always seem to get fur during the Arborstone Mission)

Sweet, thanks for the info

I also noticed a fair few trophy drops when solo.

ie. Charr Carvings, Vermin Hide, that kind of thing.
