Since my EU character was finally ported over (really, can't we have EU/NA on the PTS at the same time? Why do EU always have to be 2 weeks behind ... ), I got an opportunity to buy Hlaalu Morrowind documents for about 3,500 vouchers. Here's my feedback:
THANK YOU for finally making these available. They should have been available from the start. It's really a horrible marketing decision to leave these furnishing plans as a once in a blue moon droprate that makes it virtually impossible for anyone to learn the recipes, unless they have millions in the double digits to spend on plans at guild stores (the few ones that were actually for sale). Please don't do this for every other DLC and Chapter from here on, at least make it fair for everyone to put in the time, effort and gold cost to actually be able to learn them. So, while I'm happy with the current plans, I believe it should have been implemented half a year ago with the Chapter itself, hrmph.
Secondly, you're somewhat pushing the limit regarding the voucher cost. When you raised the voucher cost for normal purple plans from 10 to 25 vouchers, you already made them not worth for voucher hoarders to spend their vouchers on. So instead of having a steady trickle of recipes into the traders and economy, we now have people hoarding their vouchers, instead of using them on the documents, as the selling prices aren't worth the cost put in.
The Morrowind documents are 50 vouchers per, and 20 for blues, so that's twice the amount! Along with the initially 1500 voucher outfitting station, it makes me believe that you have no idea about the reasonable value of such items. I think you have looked at serverwide statistics, which show you the total amount of vouchers. And I'm sure there are certain people who have vouchers in the numbers of tens of thousands, or even more. Several people in my trade guilds have guildhalls with every attunable set crafting station and loads more, which has cost tens of thousands of vouchers, and when you look at that, you think 50 vouchers for a document or 1500 for a station is a drop in the ocean. But, to whomever is designing this, please understand that these people are an anomaly, some people will ALWAYS swim in vouchers, gold, AP, Tel Var or whatever currency, no matter what obscene prices you put on things, or how many gold sinks or voucher sinks you introduce. Just like the game mechanics shouldn't be balanced around the top 0.5 % who dish out the best damage, the game's economy and pricings shouldn't be balanced around the 0.5 % with the most gold or vouchers on the server. You're only exclusing the broad majority from participating.
I see this as an escalating trend with ESO. Look at gold costs for achievement furniture when it was introduced, basic plants and such were a few hundred, a thousand at most, and with Morrowind and CWC, we see the prices have risen massively, several thousand gold for a tree, and many achievement furnishings in the 100-150k gold category.
Same with vouchers, purples used to be 10 vouchers, then 25, and now Morrowind ones are 50 each. Crafting stations were reasonably priced first, then came the hugely expensive clockwork ones, and now you try and introduce 1,500 voucher outfitting stations (yes i know it was lowered, but the fact that you thought 1,500 was a reasonable price to begin with just supports my thesis).
So, while 50 vouchers is certainly better than paying 900k for a purple recipe at a trader, you're pushing the upper limit as to how these things should be reasonably priced.
And that ties me into my final and most important part - with a large cost of 50 vouchers for purples and 20 for blues, the documents should absolutely NOT have the daedric plans in their loottables. The Dwarven ones don't fit in a Morrowind theme as well, but at least they are still worth good coin, and you can sell them off if you don't want them yourself. The current Daedric purple recipes are found massively everywhere in the world, dropping from every Daedric mob as well as dark anchors and whatnot. People are swimming in Daedric purples and blues, and the purples currently sell for a hundred gold or sell on PC EU, the blues are sitting at 20-30 gold.
When you spend a large cost of 50 vouchers for a recipe, you absolutely should NOT pull a recipe worth 200 gold, that's for sale at every guild trader. If you want to justify the large 50 voucher cost, they should be Morrowind/Vvardenfell exclusive recipes, and perhaps the Dwarven ones with a very low droprate. The Daedric ones have to go.
TL;DR: Remove Daedric plans from the documents, both purples and blues. And please read the entire post for feedback about pricing and economy.
