The player trading system would make a huge difference if the economy was shrunk.
We have not tried proper PVP before, this would be properly programmed in PVP, not the ghetto version we created.
Bungeecord is also something we really want to do with this but we don't want to make promises.
Optiquest is barely effected by this, compared to the work that has to be done on optiquest, this is almost nothing.
You'd need to go into more detail on what a trading system means. I mean, it could be some kind of auction plugin (which I don't think would be widely used), or it could be entirely removing the buying part of the market, and replacing it with player run shops (which have their own problems with inactivity, etc...)
Again, I think more detail would be helpful. Are we talking a total pvp faction server? A pvp gamemode (As in type /duel, queues you up, you fight another player)? Some kind of /pvp command to enable combat?
As for Bungeecord, I'll keep pestering you guys till you try
It's something I really, really support.
And just to confirm, is there any ETA of Optiquest? Are we talking 3-4 months, or far, far future?
