Great to see you taking so initiative and leading the way to starting a new raiding team for those who cant attend the ones already running.
Just a few words of warning: without a regular time/date it will be difficult to get people together, just logging on and seeing if 9 other people want to raid may get frustrating.
Secondly, people who start 'softcore' raiding often get the raiding bug and want to start progressing further and hitting new bosses. This has happened with many teams, either transforming them into progression teams or they see people leave once they have geared up to join other team.
I am not saying do not create the team as your experience may be very different. Akee has a good thread in the raiding section (if you haven't seen it already) for those who want to set up new teams. Obviously as long as you abide by all of the general guild rules then you will have the support of the guild and officers and we can help give advice and such as you need it.
I think you have a point, there are a lot of people who want to raid but cannot with the hard core progression groups. If you think that you can lead the way in helping them get into raiding then go for it!
If you have any issues or need some help, I am normally around, just send me a message or catch me in game
