Due to my schedule I tend to have some time restraints in the evening hours. I find my best time to dedicate solid, uninterrupted game time is in the early hours on the weekend. I'm usually on at around 7:30 AM EST until about noon.

Are there any guilds out there that are raiding around this time?

Run with necro/pyro atm. Might be flexible.
