foreword: I love playing healer, I love dpsing while healing. With that said
It is pretty evident right now as a healer; you will hate yourself specially SCH/AST if you even dps somewhat optimally and heal you will run out of mana quite quickly ---- looking at you Astrologian.
However FFXIV design philosophy is that any composition will work for any type of "normal content" ----
What I am trying to get at and suggest is can Lucid Dreaming recast be shorten..... the fact that either Bard or Machinest is mandatory for refresh sucks because if you want to run something casually like Suzaku or what ever and I want to dps as Astrologian I am going to find myself after even 1 resurrection completely out of mana and not enjoy the content. OR refresh / something similar needs to be given to more roles (maybe monk or something) Because I quite honestly do not even want to join parties if there is no Bard or Machinest because Refresh has become almost as important as "Piercing debuff" for Bard/Dragoon synergy.... And I heard that is something the dev are looking into taking out. Because of the burden it places on Bard without a dragoon.
