Did they change the drop table in these 2 days or 3 days.  In my case Mystery Shard chance seems increased alot.   I had that feeling 2 days ago, and i tried to hestiate to ask cuz someone would say its rng..SO i just try again today.  Again lots of mystery shard.  At the moment i am posting, 3 straight drop of 3xshards.

Edit: 4 instead of 3 now just after i post
