I keep finding these simple, standard and advanced -first aid kit(s)
Every robot you kill there is always 1, couple of hours play and you easily end up like 100+ simple first aid kits in your inventory. Or you have 20+ standards or 10+ advanced kits.
No point to avoid damage because you can heal massive amounts of health easily.
Paramedics response pack, this first aid kit spam has made this item almost useless.
20 simple kits is even far more effective than carrying this thing around.
Little bonus is that area effect what it gives, but mostly cannot be utilised in combat situations.
Make the box give you 100% every use, and increase the usage time. And keep the area effect, make more of an choice versus first aid kits.
