What I understood from the the original poster is question about the innate difficulty of the content.
Let's add some numbers. If we'll assume that that players have a skill level between 1 and 10 and raid have a difficulty of 5, then a person with a skill level of 5 is neither a dead weight nor a "safety valve". If the average of all players is 5 or more, the party clears.
Now, if we'll assume that every single other player in the party/alliance is at-level for the content, the only variable is the player in question. If the player is even one level below the contents difficulty, the party will fail.
When taking into consideration looking purely at mechanical difficulty, it is not clear-cut whether alliance or raids are more difficult since it varies from one to the other.
What I said is that I believe that some of the alliances are more difficult than some of the raids and vice versa for purely mechanical reasons, requiring from the individual players a higher level of skills to pass it. Whether it is compensated by highly skilled players or not is besides the point.
