I still have a feeling the battlegroups were tweaked some how. I can often get my first win of the day in the first bg, where before it was often after 8 or more straight losses in a row.
I’m quite happy about these new dungeons, I often get almost cap in 1-2 nights these days. The Z dungeons I barely wanted to even do one a day and if I wasn’t raided, often times didn’t even bother capping. Now I cap my dungeons, do LFR, and want to do regular raids.
