phantoms have always been countered by stress attacks, either tactician or stressbot or random pilot ability.
Given that the arc is wide, barrelroll probably wont escape it unless shes very close to you. Which you can just plan for.
I prefer Echo anyway. Nobody can predict Echo's movement.
Phantoms are countered MUCH less by stress attacks that don't happen until AFTER they have a chance to shoot, unless they stack multiple stress tokens in the same attack - and even then, the phantom can choose to stay cloaked for a round or two to clear the stress.
The really mean thing about this for Phantoms is that the stress is *guaranteed* to happen before they shoot, if it happens at all, so they won't be able to use ACD OR Stygium the following round, whichever they have equipped. ANd Assaj is not unlikely to come with Tactician as well, so chances of being double stressed are high as well.
