I personally Like Rigard I would without a doubt put some effort into him. I like Grimm for his Offensive ability, not great on Defense but you will want him to raid so he is an A-grade hero to raid with so I would put some effort into him. I agree with the 5 stars being put back for a bit, concentrate on your 4 star they will get you what you need to get the 5-star resources,. Wu-Kong is really good for Titan battles so I would have that going fast. Guardian Jackel is a great hero level up fast. The only one I never really liked much is Liu Xi, but this hero will work until you get a better one, I am not sure what to replace it within your setup. My opinion would be Guardian Jackal 1 solid hit knocks out vs tickleing a bunch.
Rigard , Guardian Jackal, Boril,Cadimon might be a good line up
Caed, Scarlett, Rigard, Boril, Guardian Jackal in this order — Guardian Jackal could be switched out with Liu Xi when you go on defense she will hold up better, and if Rigard has Costume put it on.
