Team Build Assistance Please!

I have been leveling people up, probably made a mistake with Harlan, but I’m struggling a bit. What can I do for teams here? Thanks!

Donny lead, Tyreese, Martinez, Shiva and Christa.
A team you can use both for offense as for defense. At least until you ascend Camilla and she replaces Donny in your attack team.
As for Harlan… yeah, you actually did a mistake there. I have him for a few months now, and I didn’t even bother ascending him… wasted resources.

Thanks for the input! Yeah, I was desperate when I got Harlan. Had a lot of trash.
