User blog comment:Linathan/Unit Spotlight: Infinity Starsage Zeruiah/@comment-26361493-20161230065630/@comment-27076522-20161230072238

All elements and elemental mitigation are some of the rarer buffs. Standard buffs are more like BB ATK or Spark. I can name at least two units with one of those for every unit you can name with elements add or elemental mitigation on OE.

>We have Gregor and Kalon

Gregor is bad outside of FH and Kalon is less relevant with every release, as almost all his buffs are niche and the most useful ones, BB ATK and ATK, are incredibly common - you will want to use Rain or Ark or Azurai lead for almost all harder end-game content, besides specific leads like Holia, Lyonesse, and Rozalia, and all three of those leads cover ATK already, with Azurai covering BB ATK too. And no, 50% does not make a huge difference.

She barely clashes with any meta units at all. Allanon is way too squishy to bring to most content as his HP and other stats are so heavily gimped in comparison to Zeruiah, not to mention Zeru's ES makes her much less likely to die. Kalon and Gregor are hardly meta, nor is Rengaku for that matter. Zekt is useful for his LS but his abilities are less worth it and I would gladly use Zeruiah over Zekt + whoever.

You do realise that every single unit in this game can be BB gauge drained, right? Her iSBB just means when not BB gauge drained she's guaranteed to have it ready, even in situations where BC droprate is incredibly low or non-existent. You would probably rather not have Allanon in situations with BB gauge drain because hard bosses with BB gauge drain would kill Allanon anyway.

She topples Allanon, not the other way round. Until Allanon gets an OE, in gard content, Zeruiah will actually be usable compared to Allanon's incredibly squishy everything.
