could be due to serveral reasons:
1: the kraken events injects 180000 gold per day in each auction house cluster
2: divine coin event, i have read that a lot of people were making a lot of accounts so that they could acquire a shit ton of divine coins, so this took out a bunch of apex from the market. Therefore increasing apex prices, the gold sellers had to lower their prices to adjust for this.
3: also heard that there is a significant increase in bots, i expect that this will get worse when Out releases his account rotation plugin, because that brings afk farming in the hands of everybody .
4: alot people rerolled on a new server due to the server merger announcement. Inreasing apex prices.
5: just people leaving because they done with trion.
I expect a massive ban wave in the coming month or so because when illegal gold gets alot cheaper than buying and selling apex, trion which spring into action because it hurts them.
