Removing the unlimited feature will then cause players to either use the ge, which they won't we've seen first hand, or to use FC which is what most people do anyways. Even if this was implemented, no one will kill green dragons still even at that. You can kill blue dragons, black, you can mine gems, you can do so many other things that would not involve anyone going into the wilderness which is what I know you ultimately want. If there was a removal of the Ge completely, it would be as if it was player-based GE anyways seeing as how no one will even use it. I understand you want the server to be harder, which is fine, but no everyone wants a server that tailors that to it. Majority of players like the GE the way it is.
This is a Pvm/Eco server. Nothing has changed. If you cannot buy but it auto-sells, awesome. But making it solely player-based like I've seen amongst other servers that did have it, it won't be used.
