I am finding the same thing. When I played the beta, I was trying to spam Esseles as much as possible to be able to add drops to the item database site my husband and I are working on, and I eventually outleveled it enough that I could solo the instance. The result was that 100% of the drops were Smuggler items, over the course of about 10 runs.
So far (up through Mandalorian Raiders), on live, the same appears to be true.. I have not seen anything drop that someone in the party could not equip.
thats the amusing nature of randomness. I have seen plenty that no one needed drop.
Chalk it up to experience.
