Rare Drop Rates
As per previously the roll which determines whether or not a crate gives an rare is the same roll which determines whether or not a crate gives a legendary. Crates have a fixed number of cards so the rare rate will effectively eat normal cards. Crates which give rares by default will gain an additional rare if this rare rate is rolled. Also worth special note is arena 7 bronze crates, with a lower rare probability than arena 6 bronze crates and arena 8,9 bronze crates give guaranteed rares. The potential for a rare vacuum in arena 7 is probably meant to offset the additional request capability arena 7 has over arena 6.
Epic Drop Rates

Normal Drop Rates
And for completion’s sake the normal “eats” rate, despite the fact that as mentioned previously for crates that only give normal by default this rate is seemingly buggy. You will notice that adding legendary, epic, rare and normal for any one crate will not add up to 100%. This remaining “empty” % is the chance of the crate appearing as described in game.
