Suggestion: Tweak to loot rules for collection-type items

[PirateCat]

Currently, players can't roll on untradeable items like mounts or minions if they have already obtained them. This makes a lot of sense, because the item would be useless to them and it could prevent a different player who needs it from getting it.

I would like to see something similar for items that do have a secondary use but which still have a clear "collected" flag attached to them, i.e. Triple Triad cards and tradeable minions and orchestrion rolls. Specifically, it would be nice if the game prevented a player from rolling Need on such items if they have already collected them. This would strike a good balance between giving players who don't have the item a good chance to get it while still allowing a possibility that someone who would sell the item or trade a card for MGP could still get it otherwise.

This would be especially useful for loot from 24-player raids. I know that I've Need rolled on cards and orchestrion rolls because I couldn't remember whether I had them or not, and the process of checking that would take long enough that I don't want to hold everyone up for it, only to have it turn out that I already had the item that I then won the roll on. I'm sure that a decent number of other people have done the same.
