You pretty much sum up the entire thread right here. A small guild with 3/4 of a roster of casual players isn't really any better off then a large guild with 3/4 of a casual roster.
People just refuse to admit that to themselves and keep trying to compare a handful of small guilds full of hardcore DDO'ers to their large casual guilds, while turning a blind eye to the fact that their large casual guild still manages to get to and maintain a higher level then most small casual guilds ever get.
