Here's a taste from a NeoGAF thread about Destiny's upcoming expansion, House of Wolves.

On CE drop rates vs. VOG:

The Forever 29 meme was a killer for us.

We sat down and talked about the rewards for VoG and the rates vs. CE and ended up with the following: increase drop rates globally in CE: we wanted dedicated players to be around 32 or real close by the time Hard mode came out. increase the variability of perks that a given piece can roll. the goal here: players would reach 32 easier than 30, but would have more customization and options to build the perfect set (in terms of stats, perks, weapon affinities)

I get that Destiny is supposed to be a hybrid shooter and MMO, but this tedium is the shit that makes me not even want to get involved in any other MMO out there. Like seriously, I know that minutia like this is important to hardcore players, but it's so boring!

I also thought that the first expansion was a disappointment, but that was because it didn't add much content. Give me new maps! New characters! New game modes! New missions that go through the same maps with merely the promise of new guns that you can only use if you've nearly maxed out your character didn't do it for me.

I love the core Destiny game, and have defended it since its release, but I am going to completely lose interest if all they keep talking about a delivering is modified end-game content.
