Trading in my opinion is still not punished enough, for example. I'd like to hear from you what kind of trading you want to reward. The one that allows to scam newcomers? Well, they are still doing it, it has just postponed. The one that makes you buy cheap and sell it big? Still happening, it takes just longer.
Higher prices don't really punish trading. They could actually make it easier by increasing the trader's margin for error. You also mention "scamming newcomers." Any manager, not just traders, who lists their players at too high a price has the potential to scam newcomers. However, with higher market prices, prices that were before seen as scams are now actually fair prices.
