After playing this last night, I think that the biggest problem we had with it was that some models are simply better than others. I won, not because I played better, or because my cards were on fire (though it helped that they were), but because my models shut my opponent down. When I was the Counselors team, it helped to deny charges (Angelica). When he tried to kill my Coryphee Duet with Crossroads Seven damage auras, I pushed out of them or healed the damage.
There has to be a way to better balance the models.
