I've had about 10 telestos and about 10 invective. Luckily got jade rabbit about 2 weeks ago in the nightfall then got a 310 jade rabbit on Tuesday night fall.

Have my share of hearafter and invective as well. Most drop at 290. One primary so far, Red Death that dropped at 310 and it was from a legendary engram. No primary exotic engram has dropped for me yet.
