Blood Shard Rewards

I remember watching people spend their shards for Greater Horadric Caches which seemed to have a decent chance at a legendary drop (in exchange for 100 shards if I remember correctly). Was this option removed? I haven't noticed one anywhere, and I've spent like 350 shards gambling to get salvage gear basically.

I also seem to recall a UI element displaying specific rewards possible for the regular caches available in an act, was this removed as well?
