Hm. I was pretty hyped for Shera's omni, but now, not so much. Sure, she's a two turn mitigator, a definite improvement from 7*. She's got a higher ATK buff, and fills BB gauge ovet time. She also has a guarding damage reduction.

I feel like it's all just an excuse to call her an omni though. She seems heavily underclassed compared to the other Omni mitigators. The only leg up she has on them is a higher hit count. ATK buffs are spread far and wide (at least in my squads), so that's not exactly something notable. Two turn mitigation? Join the club. Her gradual BB fill also overwrites stronger buffs, meaning you need to use her before your other buffer, which restricts your sparking somewhat. You can't even improve it through her enhancements. As for the guard mitigation, that's a pretty niche thing. I've never had a use for it, though apparently it does come in handy.

Sure, her BB has the strong BC Efficacy buff, (if improved thorugh enhancements), but that means you need to BB with her, losing out on the massive hitcount (considering the spark meta with all these Heal on spark, BB on spark users, she'll benefit more from 40 sparks than 18).

In fact, I'd say the only really "omni" part of her is her stats and tankiness. She doesn't offer a lot of utility to the team besides her mitigation, and what she does offer other than that isn't exactly the best. Yes, mitigation is important, but compared to Krantz, who offers a ton of healing utility, some BC/HC buffs, status ailment clearing and elemental changing (not to mention a nice LS), Magress, who is just as tanky as Shera but also offers healing utility and even more DEF utility, and even Lara, who, though not usually used as a mitigator, can offer a ton of helpful buffs alongside mitigation if you choose to use it, Shera doesn't really stick out.
