Astrologian: what is your understanding about it?

[Zolvolt]

It doesn't matter if RNG is present or not for AST. It's a card class, not an RNG class. I'm not saying that as opinion. If RNG was the defining fact of the class it wouldn't be removed. The only thing that will strip astro of it's identity is if the cards and buffing are gone.

Even the job guide, if you really want to go into, says that reading the stars is how astro's are able to use their magic. It doesn't say anything about astro's relying on randomness to do anything. They are able to do it by attuning to the constellations. They draw the card to attune to that constellations. It's doesn't matter if the card is random or not.
