The Taken King was an uptick in story presentation, sure. And the most sizable batch of new content obviously. Endgame was trash though. After having finally had 2 Raids, PoE, Nightfalls, Trials, and Iron Banner all viable, they tossed half that in the trashhole again. And a Raid that boiled down to "Ya got one of these 3 snipers? Yeah, you win now." Any other gun type being basically invalid as actual contribution. With Raid weapons that would be the worst set of garbage if Leviathan hadn't upped the ante by just not even bothering to have a full set.
