User blog comment:Jared Grace/Sera, Queen of Blue Butterflies/@comment-3391671-20161119045215

Simple overview:
 * Missing range of "nearby." Also, if "pets" denotes anything from 's voidlings to 's spiderlings... as unique as the idea is, I don't think this passive will be favorable.
 * Butterfly swarm is reminiscent of 's, with a unique spawn on top. Rather, it does the same damage, for the same duration, with the same "pass onto nearby enemy"... copypasta, I see...
 * Blue Butterfly is simply an automatic spawn version of the on-kill Q... I am not amused, possibly because this kit could be cleaned up a bit more.
 * Free (on a shorter cooldown)? No please. On top of that, you give a second slow to Sera's kit? I believe this isn't the best way to go with the kit.
