Repair packs aren't significantly faster than using regular tools and cost a pretty penny to craft compared to the default. They get consumed if you disengage from repairs even for a second, which makes them unreliable when being bumped around a lot. My solution is to make it click-and-forget tool; when you hit that repair button with a repair pack equipped, it can either
- Restores the device to 100% condition immediately
- Attaches itself to the device and continues to do its regular repair time independent of the player
This also means a single player can juggle repairing multiple devices more seamlessly, and gives the repair pack a better situational use
