This would be adding 12k per duel. I think this would be too much. Imagine two people who are teamed and friends, they make a deal and will trade off wins, they could make 100k and 20k in 5 mins? This would, I believe add way to much money. Imagine this over a long period of time, lets say an hour. This would add 2 million and 400k into the economy, this is way too much.
