Homing Strikers are dangerous enemies on the battlefields of Nexus. Their low intelligence, however, causes their short-lived homing projectiles to pause mid-flight on the nearest target.
Homing Strikers were relatively easy enemies if dealt with properly, if you kept moving there was no way they could hit you, but stopping would make it easier.
Homing Strikers were no danger if they were alone, but in groups this could be a big problem, because you would spend most of your time ducking and dodging their blasts rather than fighting them, so use abilities like Sage's Strangling Briars from afar to weaken them or Vex's Time Bubble to slow down the projectiles.
When fighting use basic attacks on them whilst keeping track of their quantum rays because they would follow you for a short amount of time before disappearing, but by this time a striker would have already shot another blast so killing them up close before the blasts hit you was the best way to finish them.
