This is what I have : https://imgur.com/a/wiak00e

Looking for help with a team. Arena is sometimes win or loss for me. I've just been doing it without 2 healers or a stall team. As for Raids. A nice comp for raids would be helpful, like Fafnir and Vedr.

I'm guessing Vedr and Ignis will be using the same team? Would using Collette +1 for fire raid be fine and possibly arena? I asked this because I have Reiz and the link skill might come in handy, but I don't know if it is worth it because she is a +1 and I don't want to go wrong here.

Also, how is Ash +2? Should I still use him or replace him with others? Some of my units I have I am unsure if I should use them/focus on them. Like Esta for example and others. Especially since I am limited on resources and essences.

Edit: Ren is +2 now.
