Noteworthy SRs near SSR level in terms of power and usefulness
Chris. Poor girl who is the only MC of a langrisser game who did not get SSR treatment. Her abilities is SSR level though.
Undead/Monster killer. Damage and aoe heal teammate irregardless of the range from her. Damage and self heal. Random positive buffs on a teammate near her.
Sofia. Under-rated healer. As I mentioned, her aoe reset all allies' skills in range is godly. She has the most aoe heal skills out of all healers, beating even SSR healers.
Freya. OP tank of almost cheating lvl. Hits and damage even before entering into the battle screen. Sometime even killing units of low hp even before battle starts. After battle, hits again. An absolute great ally on your side, an absolute nuisance in pvp on enemy side.
Sonia. Good sub for Leon if you don't have him. Fast and hits hard.
Vargas. Our baldy tank. Sturdy and has a self ress. Ress himself when he is killed once per stage.
Eggbert. The reknown goblin slayer. (Excels in the goblin stage for farming gold).
Lot of aoe. After he cast his dmging aoe, he burns again on everyone who got hit with the aoe. (ie, 2 aoe hits in one turn)
Fana. AOE phy archer. Her archer class and flyer class are very good.
Imelda. Sorceress of the empire team. Great aoe ability and mass attack buff. Usually seen in pvp.
Bottomline: SSR are good but are mainly icing of the cake. A good team of SRs can beat anything in pve and pvp. (Especially Chris. Lol. My opponents tend to underestimate her and leave her alive, but she is the one that turns the tide.)
Which is probably why even SRs has a fairly low rate in this game compared to other games... at only 13%.
