To be honest…It is just my opinion - repair kits are useless. And was useless before. The only repair kits i have used - legendary repair kits, during time when legendary items were repairable. It’s just not so hard to get resourses to repair broken items (or even new items that can be looted from nps\chests). Another thing if possibility to repair items was only throught kits, but seems to me that in such case it would be easyer to just craft new item.
