I've a couple of problems with the new AST, mostly mentioned here already. The new card system is meh at best, but what annoys me the most is that i can't tell if it's worth buffing a player or if it's a net loss dps wise.
Also the potency now on the abilities they butchered like celestial opposition are laughable with the cds they have.
It seems they put zero effort into the class and just decided to hit it really hard with the nerf bat.
