Crafting is done in this game, there's no way the devs will ever get on top of the dupers, without banning innocent people. I got banned in Oct last year despite not having duped a thing, any automatic system turbine puts in place will end up punishing other longtime players who've focused on trading. I'm biased due to wrongful punishment, but I'm of the opinion that the bans handed out last year did not make the game better or improve anything in any meaningful way.
I think the best path forward at this point is for Turbine to stop:
releasing items/systems that rely on ingredients
selling items that use the barter interface
stop breaking the UI to prevent cheating
Turbine don't have the resources or the motivation to properly fix the underlying problem, so the next best solutions would be to:
All new named loot are dropped as completed items only
Ottos boxes get replaced with a mechanic that auto grants xp in exchange for TP. (gm's can directly grant xp, so there must be a way)
New event items are delivered as a complete item via mail.
Augments return to being an item that has to be used via the stone of exchange (ie. no more barter interface)
At this point, I think it's time to consider what happens if exploits are here to stay, If turbine could change their current (failing) approach and instead make all items obtained via ingredients second class loot, at the very least new players could/would be given useful items. Cheaters would either quit, or go back to playing the game to obtain new loot. Both outcomes are positive.
Also an apology for the incorrect banning last year for me & my partner would be much appreciated.
