My first try at using the Guild store sucks so far. The search part went OK. I found what I was looking for, price seemed great for the crafting materials. So I bought $6000 gold for them.
After I ordered the items, it took me awhile to figure out where the items were. I didn't realize the ESO uses the email system with no identifying tags as to where the attachments came from? Ok I can live with that knowing that as soon as I buy something it will be mailed to me. Stupid solution to a simple system, but I can deal with it.
The second time I decide to buy some high end chest armor from the same guild in Anvil. They had actually exactly what I was looking for at an excellent price. So then I decided to hey, lets see the quality of the light armor and yes I was impressed again. So I bought another piece of armor.
Been checking my email now to 15 minutes and no mail? The first time the email was quick, but now I'm still waiting. Finally after 20 minutes I get my items I ordered. I did a bug report, thinking that I was screwed. I'm not blaming the guild at all, they have to use the system ESO created.
Why doesn't ESo just use the same system as the NPC vendors; that is when I buy something, it goes immediately into my inventory, and give me an option to sell the guild the items that they are looking to buy at their price.
One optional thing i would also like to see implemented: next to the price there is a percentage of how high or low above the average price that the other guilds have been selling the same item for, and the rarity among the guild store that item is; for example:
Name Time Left Price Mean Rarity
Dwaren-Steel Pauldron of health 27 Days 150 80% 10/200
So this item is sold at 80% of the average cost that the other guilds are selling and the Rarity shows that only 10 guilds are selling this item and a total of 200 of this item is available.
A unique item crafted by the guild would have a Rarity of 1/1 and a Mean of 100% showing the player that this is a really rare item that may justify the high price.
This is my take on what the Guild Store should be like.
