For a while now I've thought that redstone was being held back a bit too much, but it was only recently that I discovered that flying machines were not just held back. They are completely blocked as pistons are blocked from even pushing a slime block. I found this quite upsetting as flying machines are amazing (imo). I understand that they can be abused, but I don't believe blocking them is the solution. In my opinion the solution to solve this would simply be to strike hard on any abusers, and ban them for x amount of time. But this is just my opinion, what do you guys think about redstone limitations in general?
