You’re not alone. This topic seems to come up after every single patch, and Blizzard took some time to address the concern yesterday:
I’m not trying to disparage you, but this claim is made by someone after every single patch. Every single one.
If you have a lot of data on the matter, I would recommend posting it on the Bug Report forum, so that they can investigate this properly.
Keep in mind, that with random number generation, you might be in an unlucky streak. It can and does happen. By focusing your attention on it, you can easily convince yourself something is out of whack.
As far as I know, nothing has changed. However, we can certainly look into the matter.
The proof is in the pudding (whatever that means), so if you truly feel something has changed, get Blizzard some numbers to work with and report it to them.
