So you're bad at leading a guild?
It's obvious through interviews where someone stands with being able to handle themselves in a raid environment.
If it's not (maybe you struggle with reading people, you do have enough trouble distinguishing between lfr and normal/heroic loot items) then maybe take these tryouts for a trial run?
I don't know, it seems your problems really stem from you, and not LFD.
Continue to lean on it though.
