According to the Javik/Unique dialogue wiki:
During the battle with the Phantoms, Javik remarks that the Phantoms' barriers appear to be unidirectional and suggests they shoot them in the backs.
But this is not a strategy noted in the wiki entry for phantom tactics.
Is this an actual game mechanic/weakness for battling phantoms? Or will attacking them from behind (while they have barriers up) still inflict the same amount of damage?
Also, I assume that this would only apply to weapon-based attacks and not biotic and tech powers that effect barriers, correct?
