The Taken King edition with all the DLC is $60, and the Taken King expansion on its own is $40. So what are you referring to? The people that purchased the game on day 1? No offense, but you might as well be complaining about how publishers lower the prices of their games over time, and this is a thing that's been going on forever. If you don't want to be a victim of it, don't buy games on day one, especially if you don't want to pay more.

Destiny also needs continuous content updates if they want the playerbase to remain active. I do think the content ought to be free and should be funded in other ways, and that's the route they're taking now. Destiny isn't a big enough game to leave part of the playerbase behind and give them no incentive to buy the latest content, and this is the flaw with Destiny. Because you're right, people shouldn't be forced to buy the latest content, but Destiny doesn't work that way. So, the best option is to just give everybody the content, and that's basically what they're going to be doing now.

i paid 55 buck(CAD) for the complete game on my xbone (including my gold account discount). it's mostly shit for the ones who bought destiny before the expansions.
