Aye, I've read that. Yeah I agree, around December I read an article from Bungie's research lead (I can try and find it if you haven't read it) on how to 'keep players playing' through patterns and reinforcement. Nearly everything discussed has been implemented in to Destiny. Simply reading the theory behind it seemed to knock me out of my trance-like state of incessant grinding. Obviously [i]all[/i] games' ultimately aim is for this, however, it just seems a lot more prominent in Destiny.
