Is that post-patch? Not entirely sure what time the patches actually hit. As I understand it, you'll always get one bundle of the legendary on HC now (which means the entire odds of drops change. Sigh. Not respading to see if it's a 27% chance per for the two remaining bundles), which fits my few data points. It reads as the breakdown going from 1 random, 1 party, 3 rewards to 1 random, 1 party, 1 reward leg, 2 rewards as before. But I'm not sure when the patch hit today.

From memory there's one or two L30 HCs without a legendary, though might be misremembering?

I don't feel that they really needed a buff, honestly - the rate was passable at 27%ish per bundle. Of course, what they could be doing is guaranteeing one and droppnig the rates for the others, though that still comes out to a minor buff overall.
