Yes please! I want them to actually have a use in skywars an especially Sg where people love to run away. :(
Im not sure about players but you can do this with dropped items in 1.11
They can pull players, mobs, and items. I believe in Sg you can even pull pigs around with them but Im unsure. It is disabled though on cubecraft for some reason.
I think they disabled fishing rods in 1.9 because they are waaaay too overpowered in 1.9 since it just pulls players towards you ;)
I assume you are talking about skywars for pulling people into the void. While it may be really annoying to be pulled off an island keep in
mind that the pull doesn't even work half the time in vanilla and if you are sneaking and above the player who's trying to pull you, you won't be pulled off merely pulled to the edge of a block. Also they could simply remove rods from skywars and keep them in Sg where they would be incredibly useful :( even then they could have them only in op versions of games like eggwars and skywars.
