To be fair I did check out OSRS Gold minigames found in the wild. Nearly all of these appear to be extremely "wild-centred", which means they aren't logical when left to themselves.
The Mage Arena is scary because it's located in the north and you run the risk of being attacked on your way (and equally you can't fight in as good gear in case you get attacked), all that is fired up happens in the wilderness, and removing it would be nonsensical since it's an attempt to prove that a wilderness safeguard can work, stealing creation is a camp devoted to the worship of and the reincarnation of the ghosts of the revenant that plague the godwars battlefields and the fist of guthix is an old battleground guarded by the druids of guthix where many warriors come to fight daily and get some of the power.
Activities 2 and 3 will continue to be in place, but I am aware that Clan Wars doesn't necessarily need to be a wilderness-based game. The ability to fight against one another to train could be easily transferred to Al Kharid's famed duel arena. The mages could create an interdimensional rift using the same magic as to make POHs (yes there's a story behind it:) and it would be all fine and dandy.
Given that the revenants have entered an unknown cave, it could be possible to relocate the theft of creation. The center should contain the mystic's tent.
What is the reason Fist of Guthix required to go? it is located in the wilderness of low-level, and you do not have to take anything with you there. The teleport option is available to players. You run the risk that you will get killed but it won't cost you anything. Personally, I'd be happy.
I have a question Buy RuneScape 2007 Gold Sir Amik Varze. The White Knights, (By Guthix I would like to see them have an alternative title, similar to the Kinshra) are an army, political, and social organisation. In feudal society (yes, RuneScape doesn't pay any attention to how nations are managed or the size of the country, places are too small), a knight is in the bottom of the heap, whereas a king, who is only defeated by the emperor is the highest.
