I can honestly not think of a single improvement with EOF. Sure, there has been some cool things such as new weapons and cutscenes but those are expected with any expansion. As a whole it has just made the game more dull and feel more pointless. We used to be able to build upon what we had, now we're supposed to grind even more for things that will be rendered moot in a few months - and we're supposed to do it in old or tweaked old content. What's the grind even for? So that we can run the same campaign we just ran but on a higher difficulty with rewards that are going to be worse than the things we have? I heard someone say "Destiny players don't want to grind, they want to farm" and there's very little of farming at the moment. Everything is just a grind for infusion items and most of us will probably never get past that stage before the next update - seeing how utterly boring it is to play at the moment. Edit; Actually, there is one improvement but people probably don't even know about this because I've never seen it advertised and they've made it so that the old map is hidden away in the background. That thing is that there are now daily lost sectors active on every old planet and from my runs I'd say that the exotic engram drop rate is 100 %. So it's a good opportunity to catch up on missed trophies and get exotics for infusion. I don't know if the exotic engrams cap out at any power but I've had them drop at 227. They also drop legendary items but only up to power 200.
