They have decided to keep some of the frustrating things instead of the more useful things, like as said above the lack of specific strike which in D1 each strike tied into the story of the game whereas these are just glorified side missions.
The bar graph measurement system has always been how you compare weapons. And truthfully it doesn't hold true to the actual attributes of the weapons. If you use a submachine gun and aim down sights it moves all over the place so in reality it's stability is nowhere near as high as it says on the graph, but you use The Number or Uriel's Gift and they are incredibly stable in comparison to ANY submachine gun.
Also The Graviton Lance.
It says on the graph it has 100% full stability. But with each burst of the shot as you pull the trigger, it gives a real kick and you have to wait a moment before you can take your next shot . The only stable part about that weapon is that the triple burst shot only moves upwards and doesn't shift sideways or corkscrews etc. Still it is an awesome weapon
the third shot of each burst does about 1000% of the power the previous shots.
Then the end game stuff, like the raid and nightfall power rewards. Yes they have made the end game power level more accessible to the casual gamer which I think isn't necessarily a bad thing, because they are wanting to keep more of those players in the game. But they have sacrificed those people who grind and grind the raids for that loot. So they have not really gained anything in keeping players in the game.
However, if you are not doing the raid just because you can get the same power loot from doing other activities then that is a bit silly coz it is a fun part of the game, which because of it's multiplayer mechanics and gameplay is a very different part of the game and how it is played. And there is an exotic shotgun you get from only doing the raid.
Personally I love the game. It is smooth, it is fun and the gameplay is just as smooth as the original as well as adding new animations and new enemy types within some of the enemy races. I like the fact that you can go to many different areas on each world instantly, maybe they have put too many spawn points/fast travel on each planet even.
