Which materials do we need to focus on?

I came in as a Legacy and had a somewhat leveled set of DoL's. This turned out to be an aggravating issue though, as I never had time to collect large sums of lower-level materials needed for DoH (I did, however, still have a large stack of crystals so yay).

So here's the question- to level DoH we need a couple of some materials (or none) and piles and piles of others. What are your recommendations and why for what we should stock up on as we level? Do consider both grind-able materials (300 logs>100 lumber) and targets for good triple-turn-in leves.

Just the basics to start with- 400 iron was not near enough. Piles and piles of iron. Used for Iron, Steel, and Cobalt used in Blacksmith and Armorer.
Logs of every variety for carpenter.
Malachite and Peridot for Goldsmithing leves.
Cotton and Flax for Weaver. Used up the 300 flax initially gathered and still need more.

Its just a pain to backtrack and gather at 16 XP for old materials or *shudder* shards.

Alumen and Black Alumen from mining are needed for turning skins into leather. Effervescent Water from mining makes Twinthread and Natron (which makes Undyed Felt) which are used in many high level crafter/gatherer gear recipes. I've had a few people leveling cooking ask for cloves too even though vendors sell them as well, for making +control food

You can use this to calculate your way through crafting/gathering
