Let me clarify, I don't think the game is really out of balance with fire arcs, it's more that in a six turn game the Empire can bring it's main guns to bear for 1-2 turns, the Rebels 4-6 turns in a typical game where players maneuver decently. I was a little surprised the Empire forward arcs weren't a die weaker and the side arcs a die stronger, that's all.
I did think long and hard on running 4 x VSD-I with Motti and squadron support, it's a bonkers list.
