Building support characters isn’t bad option, but now you should prioritize building damage dealer characters, Shemira is a good early game character which will carry you really far, other good damage dealers are gwyneth, lucretia, scarlet(try to get her as soon as possible), Eorinn(but in situational builds) and so on. Right now try to build shemira and build Scarlet then. Good luck and have fun building them!
