If I already have Spica and Nanaly, is there really any point in trying for Rita? Also have Shao as a backup. Her ability just doesn't seem all that great. Tempted to just keep 1 for the art and use the rest as mini EXP armours for my other plats. Have 6 so far, 7STA map wrecked me, so this is probably as far as I'll go, farming Arrows from heaven and 3STA map for healers.
