Someone on Reddit updated the loot tables though, so in theory you could take these and for each gambling category add a simple column to multiply it with the amount of legendaries on that slot per class and shard cost to get the desired numbers. For smart loot items on slots (wizard hats, wands, cloaks etc.) just double the specific item, i.e., you get twice as many wands from gambling as you would get if all weapons were evenly distributed (tested this myself by documenting gambling results from 1000 weapons).
