I know dev's were thinking about taking teleportation out for linger time and my opinion on this is DO IT!. Take teleportation away.
I think teleportation isn't in the spirit of the game also its kinda overpowered (makes milestones and gates useless)
Some people will say that it will makes trades Impossible but it's not true - you can build roads and run with a cart on it it is not that hard to run whole super grid or even two.
So don't be a lazyass teleportation fanboy and support this idea!
