Noteworthy though that there really wasn't any other way to go. With a third medium ship there are two AOEs from Constantine that create a sizable drag net. If anyone suffered for Obstacles it was he. He was the one grumbling that all his attacks at Yavaris were obstructed.He flew against kosantine right into the effect. It is like the time I faced Naboobo2000 at regionals. I flew my force right into his Gladiator line and got destroyed for it. I played Naboobo2000's game not my own and lost for it.It's not just about avoiding obstacles. It sounds like you flew really well. It's also about those extra obstacles removing choices (or penalizing certain choices). This would add to the control magic feeling and magnify his feeling of control over your movement.
