Let's begin OSRS Gold discussing wilderness boundaries. Prior to 07 there was not a safe zone. The most basic wilderness design includes zones of safety. They could be considered to be indefinite, however they can disrupt the current battles. It promotes the safe zone, and also focuses on fighting around the safe zone.
In addition, it is a detriment to the goal. The issue is whether we will get a new design for wilderness within BH worlds or the old one. This raises another issue: The current activities that occur in the wilderness aren't permitted. What is their choice and what effect will it have on the wilderness?
Personally, I would relocate all minigames (Clan Wars FOG Sealing off Deamonhiem Defender of Varrock and Sealing off Deamonhiem), but the three quests make it very difficult. Defender of Varrock, as well as the Summer questline both have significant portions in the wild. If the quests are to remain, it is recommended to complete the quest. What do I mean by that? This means that you will be on your feet alone once you have met the quest start point and entered the wilderness as part he defender varrack story. This could alter the quest slightly, but it won't alter the quest in any way.
Green Dragons, RS 2007 Gold Zombies and Chaos Ele should all be maintained the same. The most effective place to train should be a bit dangerous. The Corporeal creature is an interesting point. Although I can imagine it being fun to have barrage runners enter the cave, its boss mechanic is unique to RS in the fact that you will be banking lots due to its high risk nature. The entrance might be more appealing, as it is located just over the level 20 (telecut off point).
