As a person who plays on a controller I can tell you ast feels absolutely awful to play. In the old system you could change the cards to AoE buff cards so you wouldn't have to press up and down on the d-pad so much. Even when you did single target buff someone you had the ability to extend the buff which resulted in less targeting as well.

If you are not using controller I heard the new ast plays "alright" but I can’t confirm that.
