I received this question, and wanted to answer it publicly on the blog so there is no confusion.
Hey, I am wondering why ectoplasms are rising in price so heavily. At any other times u've seen t5 decrease in value so has ectos. and the amount of rares that has come into game from farming give even a bigger reason to decrease the value of ectoplasms. not increase them.
The only reason I can think of is a nerf to the chance of ectoplasms. Most people will claim this untrue and it has never been said by Anet.
But i did a bit of testing, just to see. I salvaged 1000 rares and i got back a return of 625 ectoplasms, this might just be that i got extremly unlucky, but i used to make huge amount of gold doing this method 8-9months ago when the difference in t5 and ecto was like it is now. The difference was even lower then, than it is now!
I could probably pull of arround 8-900 ectos from 1000 rares back in those days. keeping a return rate of 80-90% due to the 2-3ectos from the lost ones.
Any information regarding this would be great!
Glob of Ectoplasm, when I checked, was 24 Silver. The lowest buy out for level 68 rare armor was around 21 silver. So you can't just buy them outright and make a profit. Instead, you have to place buy orders, but how can you do that without understanding the chance of salvaging an ecto? Here's the math....
Rares that are level 68 or higher result in ecto's on average 50% per salvage. Your 625 ectoplasm salvages were lucky and above average! Before the nerf, your 8-900 ectos was actually unlucky, because the average was about 1 ecto per salvage. Previously, you could get up to 3 ectos per salvage, but now you can only get one.
A lot of people still don't understand how this system works, and they place buy orders assuming that they will get 1 glob of ectoplasm per salvage. This screenshot is a very common occurrence!
Instead of people competing around 6 silver for this piece of armor (which would be profitable after salvaging), they prefer to post a crapton of orders around the same price as one of the ectos. Tisk tisk! Shame, really, but you can still make gold if the prices are right on the rares (for buy orders) and ectos (for listings). Do the math and assume 1 ecto per 2 salvages.
