By Default, this is how these types of matches are; HIAC, WarGames, Cage Matches.
The problems WWE does, is that they overuse it. These types of Specialty matches should be End Fued, but no, its done regularly to kill the aspect.
Personally I think they should get rid of the Elimination Chamber and HIAC, as both have a boring concept centered on spots. With the Steel Cage you can have the same HIAC spot but not with the concept of leaving the ring to perform it.
The key rule in business is simplification, and WWE under Vince tries to make it complex, all for diminishing value.
