USE. THE. OTHER. PLANETS. Every villain, other then Savathun, just feels like a villain of the week. This is because every expansion takes place on just one planet (the new one that comes with an expansion) but I feel what made the good expansions special was the Multi-planet adventure. Bungie doesn't even need to make a whole new planet either, Rise of Iron just added a new part of Mars in the dusk palace. The use of the other areas makes a story feel more expansive, it makes the villain seem like they have weight and reach because we have go through so many hurdles to stop them. I feel the reason every mission in Edge of fate feels the same is because the developers are using only a fraction of the tools that they have on-hand. If you want to get to adding old areas, too. START THERE.
