In all seriousness, this is the issue, and forgive me for being overtly elitist about it but it's the simple truth:
High end bleeding edge 8-man raiding has to have higher execution demands than much of the playerbase can handle. Bosses have to be too hard to carry mediocre players on. To tune any lower is to alienate and bore the good players who play primarily for that challenge. This does temporarily exclude a large number of players, but that's being addressed by nerfing the content once it's no longer "bleeding edge". The real problem right now is that there wasn't enough content at launch because of important features being pushed back to 2.1, so the average players are bored with the content that's there for them right now and want to do Coil, but Coil isn't meant for them until later.
Unfortunately, the only way to lower execution demands without making the content a joke is to increase the group size significantly (which is what they're doing with Crystal Tower). In early WoW, for example, raids were 40-man but the execution demands on individual players tended to be lower to accommodate the difficulty and improbability of having top tier players in all 40 slots. Tons of people got "carried" in WoW without it ruining the content because it stayed exclusive and relevant due to the coordination challenge. Those are the two extremes, largescale content that's hard to coordinate but easy for good players to execute, or smallscale content that's easy to coordinate but hard for good players to execute. The combinations of large scale+hard execution and small scale+easy execution are not viable models for an MMO.
