Like a healing-weapon that attacks allied ships, looking and working simelar to the saw?
Would be an interesting feature. Although it would be a struggle to balance, would it be for fast repairs for air battles or for slow repairs for the slug fests of landships and bunkers. I could see people building a repair bunker/landship right behind a large bunker and would make buildings even more OP(or it would be too weak and only noobs would use it). It's an interesting concept and potentially meta changing but I wonder how the balancing would work out.
