What about delegation? Can you get a few responsible people (officers?) to take on different areas - a master looter, a person to do invites, a person to make up the groups, etc.? So that you can just be a raid member sometimes and enjoy throwing out the DPS? I know that would be hard because so often, if you want something done right, you have to do it yourself. But if it's not fun anymore, maybe it would be better to have someone else do it, even if it's not done exactly the way you would do it.
Just an idea - like I said above, I did walk away, and I was never a raid leader. I just hate to see you losing the awesome funness of being an imba, OP, fear-abusing warlock!
