A game shop near me hosts organised play. I've visited it to play Adventurers League. The DM is instead playing a World of Warcraft adventure including variant rules like a mana system. The game has nothing to do with AL, proper.
They are using actual D&D Adventurers League branding, including logos in the pamphlet and the publicity. The DM claims it's official, and when I tried to tell them it wasn't they insisted it was since, “[he] bought the world of warcraft D&D book”.
What can a player do? Can I call/write to the AL organizer and tell them that this event isn't really AL-official? Do I just stop going and look elsewhere? Do I ring up the D&D brass and tell them to slap the wrist of the DM in question?
