FoH have limited AoE and no duration, I'm use it to shutdown other supers or rivals heavy pickups. Requirements to CQB of this super is weak side. So, literally, if you allow Striker to get to you personally, while you use you own super or heavy - you deserve to die. Simple and logical.) EDIT: Less skill requires walking around by group of 2-4 guardians side-by-side with knowledge, that somewhere near them running Striker with charged super ;)
