The main problem I found that, regardless of LA, there are still MP issues because of enhanced benefic. While the instant cast is absolutely amazing, in the long run it creates mp issues that sometimes even speared LA wont be able to recover from.The longer the fight, the worse it is for astro.The aoe is significantly weaker, while the faster stronger direct heals make up for it, it just isn't practical. Astro is definitely a clutch healer and number one in regards to that. Someone stated in another thread a while back, "The ultimate wingman", and I have to agree.
I absolutely love the curve of astro and I am definitely going to switch back to it once they change it up a bit.
