It doesn't get bad until the last 2 weeks of wipe when all the regulars have farmed massive amounts of scrap that these mega structures just lay waste and become slowly not even used as much. Plus the in flux of new player joining and adding bases be it properly maintained or with out a TC just adds tons of lag to areas with larger structures which I know for a fact 90% of them are TC less and you have players build blocking areas limiting even more land to build on.
