I just obtained enough medals to ascend my next character.
This is my current main team:
Though I use this team for most things the question purports mostly to raiding and defending raids.
The plan was always to ascend Lori (Days Gone Bye) and this seems very popular with people. I’m wondering about a few others who are close to ascension level, though. Mirabelle is almost there and then I have Javier, Shiva, Yumiko, The Governor, Garrett and Gator.
I know Mirabelle and Yumiko’s stuns are more useful than Lori’s impair but she does also give attack and defense. Shiva seems useful too.
