Master Yi's Double Strike interaction with Phantom Hit STILL not fixed.
Master Yi's Double Strike doesn't apply to the Sated Devourer passive effect, Phantom Hit, and in turn Master Yi's Double Strike isn't being applied no where as near as often as it should be; in Layman's terms: Master Yi's Double Strike should be proc'ed once every other auto attack but isn't the case.
AA [1] -> AA [2] + Phantom Hit [3] -> AA [4] (Fourth attack triggers Double Strike) + Double Strike [1] (Double Strike should now proc Phantom Hit, as it (supposedly) applies on-hit effects as well as being a second attack (counting towards his flat cooldown reduction on Q and applying a stack to Double Strike); [2]) -> AA [3] -> AA [4] + Double Strike [1] (Double Strike should now proc Phantom Hit, AGAIN; [2])
