You forget that not all ppl have the time to be around at raid schedules. Doesnt have anything to do with skill imo. And ppl talk like EC is rocket-science it isnt. Anyone with half a brain can understand the game mechanics and beat it by meeting minimum gear requirements.
During our progression raid nights we were raiding 2 nights per week for a total of 2.5-3 hours. Once we had it on farm (ie cleared it in a night) we were finishing it in 90 mins, 2 hours tops.
Scheduling 2 hours a week shouldn't be hard even for the most casual of players.
