Both times the legendary was from a cache, too - each of those days I collected ~5 war supply caches, 2 paragon rep caches, and one or two emissary caches. I'd open the war supply ones first (as I assumed they had the lowest chance), then the emissary, then the paragon. I received a legendary both times I did this. I'm going to try saving up a few caches and opening them all at once again tomorrow, and if it gets me another legendary... well, then I've apparently found the secret to getting them.
