I follow everyone who say that A1S is the AST raid... Hands down !
With all your tool kit you got 0 struggle for this one

And cure III is not really a niche skill...
I'm often disappointed to see the whm spamming medica on a fight where DPS are all pack...

On the other hand if a DPS do not pack and come near me on a fight where he should... I will let him die alone ! I do not have unlimited range

Cure 3 have a great range despite what many are saying
And it's really helpful in many situation
(Plus less enmity than medica 2 since it's a single strong heal and not a HoT)
But i admit that medica 2 got the best healing potency if you take the the whole HoT
