*facepalms* We don't JUST use swords. We can use arrows for range, bombs for explosives or throwables and/or feeding horses for a closer yet still ranged attack. There could be bushes or pots to pick up and throw at people. If there is a snowy area, shovels can be used to get snowballs to slow others down.

As for the concept, I think if someone stays in a set "area" like on a beach or in a forest area for too long it should allow a map of the island to be available and that person's head will appear on the map for a short period of time. Could also say they're in a specific building if they are inside for a long time as well (hopefully indoors PVP enabled as well). Just to keep people moving.

There could be certain "drop points" where bombs and arrows/health could respawn every minute but of course if you stay longer than 10 seconds within the area of it you will take damage.
