Set Item Duplicates
I think I've seen this elsewhere on the forums but I don't remember where.
I was reading one of your early blog posts about DC where you mentioned you increased the chances of getting 2 set items almost at once. Well, I've noticed that the 3 or 4 times I got set items so far, I soon received the exact same set item yet again.
Perhaps the random number generator for the item type is being called with the same seed? Alternatively it could have just been a fluke, but maybe you should prevent that outcome -- if you want players to get 2 of the same set, you don't want it to be the exact same item, right?
