Hoping this doesn't come off as elitist so apologize if it does, but as you're not 60 with AST according to your profile are you reiterating what someone else has said or your own experience. As I've said before when all team members are working together and not slacking I have honestly not noticed a lot of issues aside from the card issues. Yes as a whm and scholar players are able to be more lax and lazy than they can be when an AST is healing them. To be a devils advocate on that I would be more concerned with SE nerfing other healer classes to put them on par with AST which from a balancing stand point it is easier to nerf than buff. People saying the other healer classes allow tanks and DPS to be lazy and that sends a message to SE that those jobs need a little more difficulty. Just something to be mindful of.
