I disagree completely.
As an active member of the graal community for the past 13 years, I happen to know for a fact that the only reason trading is enabled on PC Era and not on iEra is primarily due to profit.
Stefan won't allow us to trade because HE is the greedy one.
Edit: The reason I say this is because by there being no trading, his profit goes up by more gralat spenders. I.E. pay to win.
I see no harm in a legit trading center that would allow players to share the limited items they have earned in the first place that they no longer wish to acquire.
Edit: And what I mean here, is that there should be a trading system that PREVENTS players from getting scammed in the first place. I can think of at least 3 different ways. The system PC Era has, being the best one in mind.
Disabling the dropping of items feature is just going to lose more of your player base. (:
Give the people what they want.
