Eirika, steady breath or distant counter?

If you are building for her Sieglinde forging, I would use Distant Counter, and not use Hardy Bearing.

The reason I'd go with that is because her statline basically supercharges when you build to have the other buffs on her. She can really make use of DC and, say QR or Vantage as her B slot. However, I wouldn't put Hardy Bearing on her, since you really want to use that as a Hone or a Goad. (I like the skill, but for her it's not as useful.)

or you should just not use Eirika since she sucks. Her weapon refine doesnt help her garbage atk enough to be viable. distant counter on her is a waste too. steady breath & close def is also not great since her base def is too low to have any use.
