Not sure why people are upset. You got a game at release and you know what is in there. You paid 60$ for that. What does it matter if Bungie had 50% more content already finished at that time? Are you entitled to that content? No, you knew what you are paying for.
I enjoyed the game for what it is for 3 months roughly and I definitely got my moneys worth. I'm not buying any further DLC because I do not think that the provided content is worth it. Simple as that.
Except we didn't. Do we know now? Yes. Did we know when we bought it? No.
After the beta, there were multiple people voicing concerns that the game would be lacking content-wise, and Bungie/Activision repeatedly reiterated "the content is there, wait for it, it's there! it's going to be epic! you'll be a legend!" (I'm obviously paraphrasing here).
So we took them at their word and purchased a game that you can see everything the game has to offer in a few days of solid play, minus the raid. The only value proposition is if you see value in needing to grind gear for dozens of hours in order to be raid-ready, because nothing else in the game truly requires that same end-game gear. Yes you need to be higher light level for nightfalls and heroics, but those are just the same old content you saw sub-level 20, with a higher difficulty (aka bullet sponge enemies and more damage). There wasn't any change in the content itself.
So you can breeze through the entirety of the woefully short campaign, do all the strikes, play some PvP, and be essentially DONE with the game within 20 hours or less. Then spend 50-100 hours grinding up to be raid-ready.
This was not the game we were promised with the plethora of false advertising and false promises leading up to it. Whether this content was truly 'playable' isn't really the point. Nor is whether this content was cut from the game to put back in later as paid-DLC. The point is the game has been content-sparse from day one, against all promises made to the contrary, and the DLC has been almost as lacking as the main game in the content department.
It's quite strange that the first DLC had a raid yet the main game only had one raid. You would think the main game would've had at least 2 or 3, if a "DLC" can have one, considering that's really the end-game stuff to begin with.
I know some people love Destiny and will defend it till their dying breath, and that's fine. But there are a lot of us who just felt swindled by the whole deal, that's all.
You should really edit that mate.
