Frey is not good for AAB imo. Her abilities require you to time them during rage to be useful, and the CD are very long, so they are wasted if they don't go off at the right time. Almost any other attacker is better for AAB.
If you have Take, she is awesome for AAB. She is guaranteed to burst quickly, unloads insane dmg on burst. If you lvl her to 75, her heal gives 100% dmg cut twice, which is usually enough to keep her alive long enough for 1st ability to activate again for another round of insane burst, all without any user input. I think SSR Artemis is also good for AAB. If your hp is still low, it's actually not a bad idea to bring Sol for AAB - her atk down and heal will help keep you alive. Eros is also not bad to pair with Herc 'cos she gives a lot of buffs, but she is not as offensive as Arty or Take.
I will let others chime in for dark, since I still can't piece together a good functional dark team.
