I gathered stats for a week of ship battles and found a few things:
1) enemy tie fighters dodge 8/10 times, my tie fighter dodges 5/10 times
2) first move appears to be random. I have higher crew power, faster speed, higher ship power in several battles I moved third or fourth in.
3) Same thing applies to capital ships.
4) RNG appears to be streaky. Battles I lose, I lose badly with no rolls appearing to 'go my way'.
Based on this I have requested a refund from Apple of all money I spent on crystals since the launch of ships due to in game rewards not as promised. I spend crystals (money) on a ship only to have random results instead of the promised advantage.
