You seem new to patch releases.
Season 3 HAS NOT STARTED. As a consequence Season 3 items are not available yet.
This has worked this way since forever.
The. Season. Has. Not. Started.
Get a grip.
It was like this in DF S2, SL S4, SL S3, and SL S2. And there was no honor gear in BfA. And prior to that starts to be long ago. Obviously S1s are different because you have no gear from the expansion already.
Unless ypu literally started to ay this season, you either lie or have terrible memory issues.
