Account reset/Delete Characters and get coins back.

Iv'e been playing for years now and I donated a fair bit (Donation rank: Honored) but I've had a change of hart and would like to go back to a clean slate.In short I want to delete all my characters and get my coins/points back. I just want to change what class I main, but I don't want to let all that gear I bought go to wast, so if I'm just dumb and have missed a feature that would let me do this(I know about character trade but no one is gonna pay 600 coins for a 6.3k gs fury war) or if any staff wanna help me out it would be much appreciated.

Character trading is the only option. There is nothing else that would just give your coins back.
