Hello,
First of all I have no intentions of causing any hate or angry comments, so if you dont like the idea its ok but no offenses pls .
Second but not less important, I have some experiences from other MMOs where the player has the Trade broker where he / she can put the items to sell and can log off without any problem knowing that your item will be visible to be sold.
But here in this game, at least for me is extremely annoying having to keep logged to sell my items and concerning about disconnect issues that happens a lot and on top of that, the server is extremely crowded with accounts logged just to sell where you could use the Consignment Dealer / Trade broker that was created many years ago with this purpose. With this in mind not only people will be able to sell items off line but the server will also benefit from less players logged overcrowding the area ( crafting studio / Montt ... etc ).
Maybe this is what is intended for the staff but is just an idea that in my view will benefit not only the players as the server as well.
Best Regards
