The basic and most notorious difference between chars level is the amount of gold obtained by crafting a writ. The gold reward caps when you reach cp level.
Mats/gear rewarded from completing writs depends on the chars crafting rank in the crafting skill line.
You basically are rewarded with the same kind of items regardless of the chars crafting rank and crafting level or the chars level (non cp or cp level) - those rewards are mats, gold mats, items to sell, intricate items to deconstruct, empty soul gems, glyhps, treasure maps, recipes and surveys.
Higher crafting ranks increase the odds of gold mats being rewarded to the char. They also grant you better/higher value items as rewards.
Master writs have the higher chance to be rewarded to the char that has maximized his crafting rank in the crafting skill line.

I've never got a gold mat from daily writs. I do them on 3 or 4 characters, none which have any points in crafting except for extraction/research.
I get gold, survey maps, intricate/ornate items, and sometimes basic materials or trait stones.

I do get gold mats from doing writs at any level. They rarely drop at the lower tiers, true, but I've been doing crafting writs since they were introduced, and I can say for a fact that gold mats do drop at lower crafting writ levels. I also get the purple provisioning mats from lower tier writs.

Master writs are the ONLY thing that doesn't drop from lower-tier (i.e. non max-level) crafting writs. I've even, on occasion, gotten Psijic Ambrosia fragments from lower tiers - it's very rare, but has happened.

ETA: Crafting writs are absolutely worth doing at lower tiers. The gold reward (as mentioned previously) is based on character level, so if you have a level 50 character doing tier 1 writs, they'll get the max gold reward. Plus, you always get mats back, and with the updates coming with Wrathstone, you'll now get a certain amount of materials (15) at your crafting level, in addition to a smaller number from the tier above and any tier below your crafting level. At max, you'll get 15 at your level and then 10, iirc, from any tier below your level.

And, as mentioned previously, you still have a chance at survey maps, which can then be used on a max crafter to get top-tier mats. Plus a chance at gold mats. Also, if you're wanting to fill out your recipe collection, doing writs is a good way to get recipes.

Glad to hear that. I had this same "not at lower tiers" statement over on ESOReddit and didn't think that was right so I did some quick testing.

But I got that result. At 6 CP830 chars x 7 writs I didn't get any Tempers or Purple Prov or Kuta at Tier I over 2 days.

I also went Tier I but with the Temper Expertise and Extraction Passives plus Recipe Quality and Aspect max passives and still nothing after another day.

But as soon as I went just Max Tier with no other passives, Tempers and Purple Prov and Kuta popped.

Can I assume that the RNG at Tier I and not much higher is just really small but eventual? Any recollection if there is a Tier Break Point that starts getting at least 50% more chance?

do you use lazy writ crafter? type /outputwritstats to see all the stuff you have gotten while you have had the add on installed. i see you posted in the other thread already.

Sadly, that seems to be for the whole account, rather than distinguishing among characters with different levels of crafting expertise.

If I had even an idea of how to program an add-on, I would consider making one to track the drops on a per-character basis, as I would love to have access to that level of data. But, I have no clue on where to even start.

I've peeked into the .lua files of a few similar add-ons, that track drops, and it's basically gibberish to me

For temper materials, I do believe I get them at a low rate at tier 1, but I'm not certain. More of your tempers there will come from refining the survey dropped materials.
I don't have anyone at enchanting 1, but even at only 2, you definitely get Kuta, although at a low rate.
Provisioning: there are no purple recipes at tier 1. (not just that you won't get them from writs, they don't exist period.) Outside of event and dlc recipes that scale, the lowest purple recipes are for level 20 characters. I find that purple recipes drop much more frequently at provisioning 2,3,4,and 5 than 6, where they are quite rare.

Good points on the purple provisioning recipe drop rates. My anecdotal experience agrees.
