Also Lugina V2 trial may be coming, like Seria V2 Trial. Arus will likely be a very good unit for that, to focus down certain units and help contribute damage + BC fill. OD spam may even be important there, and he contributes to that too.

As for Shera, more damage reduction is always better. People who don't have her should just wait until they release a unit with more reduction though, because inevitably they will at some point.

The other two are very mediocre. Ragshelm at least has prospective use in Earth/Water FG.
