To me they are one in the same lol I remember when the only game making extra content was cod and they were only giving 4 maps for 15$ and they were played out in one sitting so idk how u can be mad that 40$ got you the crota plus more pve/pvp events and gear not to mention how many levels you can't get without the expansions. To me it's worth it but then again I don't play 24/7 so I have exotics to still chsee
