I know that the product descriptions list what comes with each version, but I know in the past with other expansions that you didn't need to get the higher priced ones because they included content you might already have. Are the seasons that deluxe describes that past expansions or ones that will be released in the future? If I already own everything else is it worth getting the deluxe? I've sunk thousands of hours into Destiny and I took a break towards the end of my Masters' degree program. I am now looking to get back into it. Thanks!
