Nats Should go to the 300 they originally were if i'm correct about how the pricing will work etc.
I doubt that Nats will rise a lot unless a mass ban happens as the supply of them is huge atm. Yet I can't see them falling down in price either, so just to be safe I would buy them now.
For an avid runecrafter like myself (top 200 - all double nats) I would love that. Finally some REAL profit.
Point being that there will be a mass ban in all likelihood =).
I wouldn't get my hopes up. RS economy relies on supply and demand. At the moment the supply is huge thanks to the botters. Because of that, the price of natures is unlikely to go up, as there are more nature runes entering the game everyday.
I've got 400k in the bank hoping it goes up
