Because Raid Affix are good ROFL.You can't even get the Azerite gear with the raid affixes from M+. As for Azerite from M+ for most you just have to settle for being able to buy a random piece from the vendor once every 3 weeks and hope it rolls good. Non Azerite pieces will be ilvl400 base, with a tiny chance to forge. If you are counting on that, you should also take that into account for your raiding gear (which has a higher forging chance btw) and just call M raid gear ilvl425 (capped). Your M+ gear is basically on par with HC gear, which seems reasonable.
