New BG ideas

Here are a few ideas for new Battle Grounds, which could be implemented for WOTLK. None of these ideas are unique per say, but might be fun to try to mix up PVP a bit.

1. A BG similar to Eye of the Storm where you hold areas until you capture them (minus flag runs), yet it takes place on floating islands. Each person entering the BG is given a trinket to summon an epic mount and there are 5 areas which can be taken over, but none can be reached unless flown to, and the grave yards are based on starting areas and none of the opposing faction can enter that area so no res killing.
2. A flag capturing area similar to Arathi Basin, with 5 areas, yet each area takes place on a tall tower over a huge lake. Each tower is connected to two others via bridges, and if not by bridge, players can reach other towers by taking the long route of falling to the water and swimming over and climbing up.
3. Again an EOTS type area minus flag running, yet the entire game takes place in a giant castle, each team trying to conquer a certain valuable area of the castle such as the armory, library, courtyard, stables, etc. The castle can be a giant maze with interconnected passages and secret doors. The idea is from some of the old games like Quake 2 and Unreal Tournament maps.
4. Finally, another idea borrowed from Unreal Tournament where there is an attack and defend area. The attackers assault a defended area to reach a goal (all deaths taking longer to resurrect so there is caution on each side), and try to break through a defensive area to capture a target. They are given a time limit for this, perhaps 10 minutes. Once captured, the sides switch, and the attackers defend and vice versa. If the original attackers took less then 10 minutes to capture the target, lets say 8 minutes, the new team attacking will only have that time to capture the target. Obviously this is a new way to do BGs altogether, but once again it can breathe a bit of life into an area which has gotten a bit stale lately.
