If we remove the fast travel before we have another way to travel this world, we'll ruin the game. The trade is hard and only with the travel one can trade. The trade give an important quest, it give the meaning that you boost the q of your stuff also if you're not a griever, so we must protect the trade for the seek of the game.
But surely the jump travel is a temporary bugged solution.
I'm sure jorb and loftar already know this, we need horses and all the kinds of travel enjenery we can, with roads, safety docks for boats and what we can think about it.
Only then we can remove the jump travel without danger. If we remove this now, we risk to kill the last light of trading and contact between players.
(Ps: the "fire" is usefull to call your friend near you. If they decide to remove the Jump travel, should be good if they keep at last the Spawn near heart fire.)
