One thing I'd like to say to the Lootmaster conversation as someone who has lead and co-lead statics.

Being professional is difficult as a static leader, especially if you have limited or no experience, yet don't want to rely on another group fitting for you. I generally give people benefit of the doubt when being new to raid leading, because there is a lot of things to consider depending on what kind of group you want to create.

The biggest problem in general is communication and the sub-problem of people not being honest about their thoughts and ideas. A lot of things can be pre-planned nicely, but if you procrastinate with it you will end up in situations like many of you described where rules are made up on the fly rather than discussed early.

It is prudent to have an online loot sheet and actually reach an agreement to how loot is distributed with nothing left to interpretation.

I encourage both members and leaders alike to reach out to each other if things are unclear. That way if someone ACTUALLY walks out of line you have a clearer case.
