PVP Healing Advice Needed, PVP and Astro

Just wondering, i've been pvping as astro since Seal rock was released. So far i've been having fun, however now with the new astro adjustments for 3.2 i'm wondering if I should stick with it or not.

With its effect halved is Nocturnal Sect worth using anymore?

If not is Astrologian worth using in pvp while in Diurnal Sect?

Should I try switching over to another healer like White Mage or Scholar?

The main problem I have in pvp as a healer are the spell interruptions, I had that problem while I pvped as white mage back before 3.0.

As a White Mage I found that I had to Pillar hide a lot more in order to get spells off, but sadly I found it a lot harder to heal in a 4 v 4 setting while not in a premade due to teammates sometimes wandering off or running away from you.

I'm also afraid now that they are removing the TP requirement for sprint it will make healing as a White Mage or Astro in Diurnal Sect a lot harder since Bards/MCH and Melee dps will be able to keep up while you try to heal behind a pillar or structure.

AST will still be the most mobile/instant healer of the 3, and still has a lot going for it even with a slight nerf.
