The Taken King update was terrific, no doubt. However, the April Update (known lovingly as the Taken Spring) is where the game REALLY hit it's mark. (I've played Destiny pretty much exclusively since launch/vanilla, so I can easily say the game is at a point where it's the best it's ever been).
The April Update eliminated the "Double RNG" for gear drops in the raid, and other end-game content. Previously, you had the first RNG, which was even getting a drop at all. Then the 2nd RNG kicked in, which was what light level the gear dropped at. You could get gear drops that were well below your light level, which caused many players to stop grinding to get to the light cap.
NOW, any piece of legendary equipment dropped in the raid/end-game is guaranteed to be no lower than your current light level, and can max out at something like 5 points above. So there's constant progress towards your goals.
I really wish you were on PS4. I'd be glad to run any of the raids or Iron Banner with you.
Oh, and Rise of Iron is out in a little over a month. Things will only get better then. New missions, raid, strikes, gear, and (what I'm MOST excited for) the ability to choose what type of reward you get from faction level up packages! Woohoo!
