TL;DR
allow entities to increase or decrease the health per repair pack, probably via multiplier.What?
currently repair packs heal the same amount for all entities. this is an issue if you wanted to make certain entities more expensive to repair.for example, I wanted to make tanks use more repair packs because ramming with them is cheap, and does a large amount of damage, but cannot do so without decreasing the durability of repair packs, which increases the cost to repair all structures.
