Sadly I have succumb to one of these. Seeing as I had done this so many times before, I didn't believe this game had these sort of low lives, but I was proven wrong.
Basically I was trying to buy a Hunting Blade, this one character, Lexaneous, told me he'd craft it for me it for 20k if I gave him some of the mats, and 2.5k to create it. I was right next to him, gave him the crowns, and mats, and he just logged off. This sob, didn't take much, at least considering how much I have so far, but it's still wrong, and disgusting to see people who actually resort to this type of behavior that makes the game that much more annoying. I was hoping to be able to trust others, since truly this isn't a game about being the "best" and all was based on just looks pretty much as stats/level deal with armor/wep tier, but it happened still.
This is basically just a warning, since I know moderators cannot do anything for me as I was the one dumb enough to trust players.
This wouldn't have been a problem if they have a better crafting system by allowing one player to craft with another player CE, crown, materials, crafter fee and confirming message to both party.
