Really just posting this in hopes that the developers can see some constructive criticism for what they have shown us of White Mage so far. I think the lilies are definitely a step in the right direction. However, I don't understand why they proc from Cure and Cure II only.
With a 20% proc rate, you will need an average of 15 Cure I or Cure II to get 3 lilies. Now, for me and for most white mages I know, in an entire dungeon run I barely use Cure even twice because Regen, Medica 2, Asylum, Tetra, etc are all very great skills that can take care of most healing, not to mention Holy's stun lock. That means I am going most of my dungeons with zero lilies, unless outgoing damage from bosses and trash has been increased so significantly that healers must use most GCDs on their single target heals (in this case, I will be very impressed at the huge change!)
I think White Mage would be in a great place if only Lilies and perhaps Confession stacks could proc from either any healing GCD including Medica/Medica 2/Regen/Cure I/II/III, perhaps just ticks of healing over time (at a lower rate than 20%), or even from DPS skills like Holy or Stone. All of these are skills that most White Mages use more than Cure in both dungeons and raids.
Even in a raid, as someone who has played White Mage in all raids since ARR, it would be very unusual for me to use Cure even 30 times, or about 6 lilies throughout the raid.
Like I said, maybe the damage output in dungeons and raids is going to be increased in number and frequency so much that healers need to spend most of their time using single target heals like Cure and Cure II. However, through all of ARR and HW that has not been the case.
As a more minor suggestion, maybe some control over when lilies are spent would be nice. Divine Benison is cool, but with Assize, Tetra, and Asylum all consuming lilies upon use, those are pretty frequently used skills in our tool kit and I don't see us being able to hold on to lilies for very long (if we are even able to generate them in the first place).
Anyway, with the simple change of how lilies and possibly Confession stacks are generated, I think white mage could be in a fun place for Stormblood. I look forward to the developers hopefully working with us on White Mage in the future .
