Cheers for the reply, Harunyahya.
I think you've misunderstood my "Duel deposit" system.
The player who wins the duel does not get the duel deposit as a reward, so they're not going to be receiving, for example the amount I used in demonstration, 10,000 gold, whether they're the higher level player winning, or the lower level winning.
The higher level player, if he wins, would get his deposit back, essentially taking him from being down 10,000 gold, right back to the amount he had before the duel, plus he would make some XP and gold for winning (Which would be a small amount, due to defeating a lower level player)
The lower level player, if he wins, would not get any gold from the deposit. He would purely be getting the XP and gold for winning the duel, nothing else.
The duel deposit system's purpose is not to reward players, but to combat exploits,
like higher level players deliberately losing to lower level players, or bots being macro'd to lose.
Also, Duel deposits wouldn't affect everyone. Just a higher level player duelling with a much lower level player.
Players duelling other players of the same level or higher would not have to pay a duel deposit.
This would discourage higher level players in plate, with a great sword duelling with low level players in a robe with a wooden stick, while also discouraging high level players from deliberately losing to lower levels, and bots macro'd to lose.
