User blog comment:Crimson Storm Mich/Future Units Preview v2/@comment-27691408-20161218040009/@comment-26697283-20161218041053

Well they're legacy units, there are only a few legacy units that is actualy really strong(and by that i mean they are still very useful) even now like Elza, Sirius(well he is kinda slowly out of the meta right now), Krantz, etc. I always think that Legacy Omnis are units that Alim uses to test out new mechanics or just pushing it out for long-time players and F2P. Shera is an example of the best of both world, Alim gave her this OE to reward old/f2p player and test out spark dmg mitigation. Stuff like that, yes it is not noticeable(the spark mitigation) but maybe in the future they'll expand on it.
