Purely
I never said its an exact 15a shield neither i told the person to sell it ingame very fast but i gave him a range to start with so he does not get scammed for a like 5e or 50e offer.
So maybe u shake ur head to fast that your vision gets a bit blurry. I suggest a focused view on the monitor next time 
So for clearing Purelys missinformations here:
a gothic defender struggled at like 10-15a
echovalds are more searched liked skin so above 15a+ depending on interesst the prices vary pretty hard these days so i would tell u to put it for sale and give it some time.
Also the Goth struggle was staight facts. i dont grab numbers out of the blue like it seems u want to make other people believe here.
THE ONE RULE most people agree at the pricecheck section.
U cant forcast the exact selling value of an item
I will back up my quote here that the "q9 Echo -5/20 +30hp" is an above 15a shield and a sale here is the best idea. The 50a you give as a value you give is a fictional number at this point wich the market will see if it agrees or not. IF it was a 50a shield the market would have shown it in the auction,wich i suggested to do,with a 15a SB basicly wich seems over all reasonable in my eyes.
So now wanna Making people believe i or we ASTRAY him seems a little grapped out of thin air ( wich for me somehow implements you wanna make people believe we would benefit from that situation, wich isclearly not the case) Its not like i wanted to buy it or bought it. I am Not like a person that wants to buy a ~400a 20/20 healing rod,while also beeing the same person that pricechecked for around 30a.
What basicly happens here is You just put fuel in a situation wich cannot be fixed anymore and try to cause some kind of trouble where u positioning yourself as the "generous good guy". Not a PURELY new behavior?!
