They are indeed primarily PvP items, though they could all have some use in PvE that's not their primary intent Think of Backlash like an EMP that causes the ammot to cook off... It's a good effect but on the downside you basically lose your super for the entire match for the sake of getting 1-2 kills tops (Might not have been clear but your super is expended when you use it.) Gridlink would indeed apply to any sniper type weapon, including in PvE. Geometer might need tweaking, maybe just stop the first precision hit each life or something? The idea is to give people options against snipers, but these options require them to equip certain items. They can't use things like the Ram, or Twilight Garrison that might be useful more of the time.
