Don't mind what it is personally, I just want some other coin source as soon as possible so we can actually test some sort of economy out
Marketplaces are essentially just placeholders at the moment until we all don't feel like we're clinging on to our warp funds!
All we'd need is 2-3 repeatable quests of equal difficulty handing out coins to give us some sense of an economy, make the handouts as low as you like until you've planned it better. Even 1c given for 15 minutes of questwork would stop the sinking ship
We're all playing a vastly different game from what we will be in a few weeks time anyway based on what I've seen of the skilltrees, don't be scared to make a minor economy change in the mean time
