I transfered servers yesterday and tried to come up with a way to double up my gold. Surprisingly enough I tried something and it worked! It kinda sucks that you gotta pay 25 bucks to do it, but its definately worth it if you have lots of G IMO
Frist: Place your character inside an instance
Second: Trade your gold to your RL friend.
Third: Run out the instance and start the character transfer.
Fourth: Place a ticket saying that your account got hacked a few days ago (give a specific time) and an unauthorized transfer was made and some items/gold is missing.
Fifth: Tell your RL friend to spend the money on w/e has value.
Last: Wait about 2 days and you will have your gold. Sell the items your RL friend bought and you are GTG!
Worked for me! Have fun!
