Nobody bases his offer on a market price when offering on a Centurion, for example. When market is 350k, people know that it is overpriced and real item's price is 90-110k.
Azurite forces always were sold for 25-30k on forums and for ~40k in the market, so i am not lowballing.
You'd better accept a 50k offer, these forces will not be sold for this price later.
