I was absolutely dead set on hard pulling Lunera all yesterday, I was really looking forward to the big Friday pull, but now I'm going to completely skip her... probably.
My thought was that she would get something in between +1 or +2; 60-80% just to keep her relevant. +40% stat buff is completely pointless given its no better than even Rain's Leadership (Or Tilith's Celestial Light) with minor healing, and she's completely immobile for 3 turns. Having an attack unit immobile for 3 turns is absurd unless the payoff is good.
But good magic attackers are always welcome. Her buff/nerf to her Arrows is interesting. She peaks at 6 turns vs 10 turns but is stronger each turn. Meaning she's 25% weaker at peak than JP, but climbs faster. While I wish GL maxed at 8 turns so that it matched up in max output, its a necessary adjustment.
However, given her unique frames, and given her unique dual elements, she really needs more than one of herself to chain up. So getting at least two of her is going to be crucial. I really wish her Areola ray was Holy with either Fire or Lighting instead of Wind, so that Ace would be able to act as a elemental imperial for her).
Ramza enhancements was released last September (2016) in JP, meaning his enhancements were released a month before the JP anniversary. Zarg is obviously meant as an expensive stop-gap to bridge the delay. Which much like WoL is likely going to go on a while. GL meta definitely is more balanced, if not a little more drawn out.
