I've had a recent interest in crafting, and have been struggling to get reagents I need, but my friends have these, and don't need them. So, they want to give them to me, but can't. So I thought it would be nice to be able to trade reagents.
That's a great way to lose reagents to Bazaar campers. The Bazaar's inventory is universal across all realms. I personally like this idea.
You must be extremely slow if you are losing things this way. I've never lost regents doing it like that you just have to private message the person buying them so there's no time for anyone to poach them. I don't think they will allow trading them directly regardless. It would make crafting way to easy.
