Would like to have future market rune changed

Say you need 100 Gold to buy a item. of course you go -100 gold into debt.

However. lets say you leave fountain right at -100 gold. that debt should be doubled. so... -100 gold = now -100 gold. (-200 gold total)

The reason i would like this better is because at times when you leave the fountain at -1 gold and dont wait a second... your taxed quite hard.

so if i was to leave the fountain at -1 gold. once i left, it would be -2 gold instead. (-1+-1=-2)

-50 gold leaving fountain now becomes -100 gold total.
