User blog comment:Crimson Storm Mich/Future Units Preview v2/@comment-26944381-20170529221617/@comment-27462814-20170607204432

Millia beats Savia tremendously if you're against more than 1 enemy, Regil's spark buff is no better than almost every recent GE spark buffer and more upcoming JP units, and he is by no means the best damage lead. He doesn't even come close to it.

Also Sakura Miku shares the same crit damage buff with Lid, and realistically neither of them are top-tier.
