Actually, commons being in there aren't exactly what you think.
Yes they are in there(to help nerf them a little bit), but they aren't actually as common as they are normally.(Which could be a good or bad thing, it really just means you shouldn't get them as often as normal)
The reason why Crescent Crates were so much better for getting Legendary items(and others), was because most of the items were not added to it's drop table, unlike item crates, which would automatically go through the global drop table and add items to it's table.
So Crescent cases have fewer items to attempt to roll for upon opening. I added one new tier to their drop table, with a lower chance to acquire than normal(much lower chance), I felt it would be best this way. What you see in the display is not entirely related to the chances to receive the items you see(only for speed purposes, there is no trickery to make you land next to a rare item).
