My raid group is currently desperate for a healer on Silver Hand, Alliance side. We raid Fridays from 7:00-10:00 pacific and on Sundays from 4:00 to 7:00 pacific. We're currently only 4/6 in normal MSV and 1/6 in normal HoF, but that's mostly due to lacking a consistent group from week to week. We are part of a raid organization on Silver Hand that runs upwards of 50 raids per week, so there are plenty of opportunities to run alts or run with other groups on weeks you can't make our raids. It's a fantastic community with a chat channel full of active players who are always willing to help out with crafting, questing, pugging world bosses, etc. My specific raid group consists of mostly guild members, but being in the guild is not a requirement at all. You would certainly be free to join our guild, if you like.
We're always looking for DPS and tanks as well, so even if you aren't a healer, feel free to read the additional details and post with any questions/comments.
