Motion sensors and grenades are more usable than the repair kit. However the bug needs to go. Other than that it is wasted
At least you won't see me using it, and:
Trust me, i am the technician.
The only use for it i see atm:
shrike loadout does not need anthing besides a repair gun and a thumper. Therefore the turrets as warning and the repair kits somewhere behind the base would help to quickly go through a repair lane.
