I mean, essentially, that was what the Server Summits were about. Building that bridge between all of it, and tat's what this site was offered up as. So, I think it's more a matter of starting? I wouldn't mind assisting in filling out some raids and what not. Of course, my primary concern has to be my guild, but, I see it being beneficial to both guild and server.
I will pass around the BCO channel in guild as well.
In terms of progression, though, I think it's an intimidating word. Folks that are hardcore Progression have strict requirements, schedules, and are masters of their classes/roles, etc. So that can be intimidating to anyone who is raid-curious when the word "Progression" is used.
If we wanted to start a "new raider friendly" event to get more people doing them and learning them in a relaxed environment, that could open them up to doing more as they learn more, you know? :) I'm all about the teaching!
