Armor healer = struggles if not in armor emblem

Eirika is basically useless in a mixed team or atleast will struggle to heal the other teammates since she won't be able to get to the otehr teammates with armor movement or if the team does not have a flier with guidance.

yes there is repo, that they can just repo her closer to allies but that is a waste of a turn that could have been used efficiently. and there is also Physic+ so that Eirika can heal from a distance.

though Eirika will definitely help armor teams alot, if the team does'nt have armor march then the team wil msot likely be close together, making it easier for eirika to heal.

Eirika is a really weird unit, since she's a support unit yet her movement does not help in support non-armor emblem teams, most likely she will be the one getting movement support.
