The Mage Arena is cheap osrs gold because it's in the far north, and you're at the risk of getting attacked while you travel there (and similarly, you won't be able to fight in as good gear in case you get attacked) All that is fired up happens in the wilderness, and removing it would be absurd as it is an effort to show that a wilderness safeguard is possible, and that stealing the creation is a camp devoted to the worship of and the reincarnation of revenant spectres that plague the godwars battlefields and the fist of guthix is an ancient battle site protected by the druids from Guthix where warriors from all over the world are battling daily to gain some of it's strength.
I agree that the actions 2 and 3, as well as Clan Wars, will continue. Additionally, Clan Wars does NOT have to be wilderness-focused. Clan Wars could easily be moved to Al Kharid's famous Duel Arena, where they could fight to train. It is possible to have the mages create some interdimensional connections with the same method that brought about the POHs. (Yes there's a story :D). That will work well.
It might be possible that the revenants, who are now in a strange cave and are stealing creation, can be relocated. My opinion is that the camp of the mystic ought to be in the middle.
But why does Fist of Guthix have to go? It's located in low-level wilderness. There is no need to carry anything. Teleporting is an option provided for members and, it is a good thing, because there is the possibility of being killed, but you don't lose anything. What's wrong with this? Personally, I would be happy.
I have a concern regarding Sir Amik Varze. The White Knights, (By Guthix I would like to see them have a better title, like the Kinshra) are a political, military and social organization. However, in feudal society (yes, RuneScape doesn't pay any attention to how countries are run or the size of the land as the areas are too small), a knight is at the bottom, while a king, who is only defeated by the emperor, is at the top.
Amik, if he was ruling over rs3 items for sale king’s steed surely he would be able to have a peerage such as the Grand Duke? This would also make Burthorpe a principality (I'm thinking that the principality is huge and that the town is the capital of it).
