This is, of course, one of the aspects that will likely happen. The other issue is, of course, the problem with re-building the game's economy. With everyone starting at scratch and no gear and/or items that can be bought and sold except through the old-fashioned "bank sale" format, it's pretty much going to be DIY for a while. Everyone is going to have, essentially, the same goods and materials as everyone else and no money. As such, there will be little, if any, player to player trading going on.
I think it'll be the complete opposite. Botting will be epidemic in 2007 servers as people too impatient in the race to the top cheat their way up either by botting directly on their characters or real world trading gold. It wouldn't surprise me one iota if the first whip to be claimed was done so by a botter/goldfarmer and sold for irl money.
but I think it will be less prevalent than the main game, and hopefully almost non-existent for a while.
This was the same issue that happened when they reintroduced RSC. As a result, you're going to have people buying and selling crap in the stores again, which means that sold goods will plummet in value and bought goods will rise. No one will make money and everyone will be poor and [bleep]ing about it.
Ah well, I guess some people will enjoy this system, like the 120 or so people still playing RSC daily ...
Im assuming rather than gold trading it'll be resources. Like my 50 logs for your 40 ores. Which is quite nice. As it suits both players trading.
