Since you already have an Ares Kai maybe you can make him Ninja and take Shizu other paths.
Shizu with Hera faith is suitable for Assassin or Magebane due to their skills make use of CRIT stat.
But it is really up to your team setup and what you prefer. Since you don't have your team setup here, can't really comment.
Samurai also has a good aura if you have a team which utilizes it.
For Teresa, you need the same class for limit break. IMO, priest path is the way to go if you have no main healer yet. Hercules faith is not bad for healers.
Thanks for the input Bunny, as of now my team consist of
3*Leon
3*Shizu
3*Kai
3*Teresa
and a Placeholder until I get something better, I used Dark Baron 4* (No Aura) for now
As I said before, I'm very early on the game so I don't have a decent composition team just yet I guess.
Regarding LB, same class means same class from the same path? (e.g. Inquisitor + Arcbishop) or the exact same class? (e.g. Arcbishop + Arcbishop)
Note: QA for newbie thread is dead? Because I got reply here but not there.
Since you're just starting out, your future team setup also relies on the heroes that you will pull from your summons.
If you really don't know which class to choose for Shizu and have no preference, I would just build Kai Ninja first, you will definitely get to use him for gold mine and such.
Then you can keep Shizu for the either Magebane, Samurai or Assassin. Wait until you complete the story mode and guide quests to see what other 5 stars potential heroes you pull then start building your main team from there.
Regarding LB, as Xinhuan already mentioned, you need exact same class not just same path.
