It would be nice to see, but then I can't help but saying having vercure increase white mana would only aid people soloing content. I wouldn't entirely object to it decreasing the gauge though. Or the potency of vercure depending partially, or entirely on how much white mana one has accumulated
P.S. I feel deeply sorry for anyone who suffers with delay when on this class, I wouldn't wish it upon anyone (a tad salty)
