Reaver's run.
To simplify things, we get 2 named items in the chest. A Cloudburst and a Dreamspitter. Cloudburst up for roll.
Player A rolls for it. Player B rolls for it. Some other players roll for it as well. Player A ends up winning the Cloudburst.
Now.. Player B is the one who got the Dreamspitter. He tells to Player A that he'll trade his Dreamspitter for the Cloudburst, and Player A agrees.
I find what Player A did to be wrong and it annoyed me. I consider this to be as bad as proxy rolling. Is it me or is it just wrong to roll for loot that you're not going to use? I'm not even talking loot for your next TR life.
This is basically the same as me rolling for an item and then telling the ones who lost on their roll to bid for it, since I'm selling it to whomever pays the most.
