Learning how to properly play AST

[Nekotee]

I want Astro to be the best healer, but it ain't gonna happen for awhile by the looks of it. The kit is just too restricted.

I do suppose that you're speaking about the DPS toolkit...
Because in term of healing the toolkit is fine. You can deal with all the situation with all the spell you have. Plus if good rng your card will ease it up even more.

...

By the way, you said that a class that have a dozen more heal or healing CD is better...
With this statement
Whm is first with one more ability than AST
Ast is second because SCH is last with nearly no healing spell beside physic and adlo

It's not how many spell or great CD you have that make a good heal... It's how they are used and fit the situation

Sorry nothing is obvious
And the AST after boost is on par with the other, no more no less
