I always have so many questions for bungie. One I was thinking of today is how engrams work. Engrams seem to have some properties roll when it drops and others when you turn it in. I desperately need plasteel so I collected engrams from my hunter when running weeklys and gave them to my titan. When I turned them in I got an even mix of hunter items and titan items. That seems like a complex system with several variables I hadn't expected. Apparently it matters what character finds them and what character decides them. Post all you questions here and maybe someone from bungie will address some.
