Astral Glory. Fiendish Leather. Lightweave Cloth. Chemirine. Argulite. Lightsphene. Labradorite. Florid Malachite. Hesselian.
Never before have we had new profession items for every profession in a simple patch. This is like a new tier of profession items. When do we usually get this? In a new expansion.
Then we have the Vindicaar moving with us from zone to zone. Pretty redundant in these small zones where you can teleport back and forth anyway. But if this was a whole continent with 5 big zones, the Vindicaar could have served as a command center for the whole expansion. Like our Order Halls in Legion or the buildings we create in every zone on Draenor.
It looks like the Argus patch is the groundwork they did for an Argus expansion, before they scrapped it and turned it into a patch instead.
