people say nay or yay on suggestions because they are supposed to, not all are shut down but the ones that people dont like or think is a waste of time usually are. this would not only be a massive waste of time (since staff would have to literally build all the rails, but it would also be pointless and ugly. you can tp to a random res already and not have to move at all and many of us dont want a subway system/rail system on or near our reses and since i have 5 of them i could block a considerable path to others. now there are other suggestiions that the community has liked or tweaked and then liked. (such as rainbowchins suggestion to make zombie pigmen become aggroed when they go through a portal into the overworld)
