Aion had something similar it was an expensive totem you could place and use in PvP zones for your group only to spawn on.. Forward camps are nice and all but when a small group tries to lay one down behind enemy lines the entire server decides to use it and it's gone in 30 seconds..

:::IDEAS:::

.Make it expensive with very little AP return on spawns.

.Make it usable for your group only, you can not spawn on it if you have a group larger then four..

.Make it have limited spawns, eight or less..

.Make it so it has a limited shelf life (couple hours) or the totem disappears if the player which placed it logs out for a period of time.

.Make it have a camp style noise (people laughing pots clinging) if enemies are close to it so it can be destroyed (we used to love hunting these totems in Aion they had a humming/beeping noise..

Make it small (campfire and a tent style) the noise is what people hunt for..

.etc

Would love to see something like this implemented small gang groups need more in PvP any one else !?
