No, it says you might now get rare or purple rewards for certain raids. They drop less in actual action. Not only is this the most (only) logical conclusion, this has been the seemingly universal feedback to the patch.
Regarding what you get during the raid, that's awesome. Of course, this being a completely random loot game and all, YMMV. Again, the general consensus is the loot system is broken and the grinding is flawed. You could have an inventory with 12 exotics and 20 legendaries and 60 shards plus 99 energy, doesn't mean anything.
GAF feedback seems the same... some got Legendary and others not... the people that didn't get are being upset so trying to says it is less but for example my case I already got 4 Legendary Engrams since patch.
The drop rate seems to be normal.
It is the best loot system in any similar game I already played... it works and it is fun... to be fair I didn't have issue with the Purple giving Blue too because I got 2 Exotic and a lot of Purple from them... and a lot of Legendary from Blue too.
