With the PLD rework the job may have been "more viable" but it lost a lot what i liked about the job, at that point i rather my job still exist as it was then "be more viable" of course I'm not aganist balancing jobs out but SE's way of balancing is to change it's uniqueness and generalise it into the other jobs.
This rework to me screams of they just have no idea how to actually make astro appealing to astro players so instead they're generalising it to the point where astro players don't like it, while other healer players *might* pick it up... I'm sure it will be more generally popular, as astro wasn't a job for everyone... now its a job that can likely be picked up by everyone. But where do people who liked playing astro go to? I don't think other healers will appeal to them... they're already... snoozefest, most likely they will go and play DPS roles just to have fun (or quit), some will put up with the rework, I'll personally try it until 100 and if I don't like it im not touching healing In DT.
I guess all anyone can do now is voice their concern and hold out until 8.0 but I doubt that will change anything, I believe that statement was said so people can have something to hope for then be disappointed by the lack of redesigning or the game getting simplified even further.
