As i understand it, in regards to the Red Banqueters battalion, the general consensus goes as follows;
If a required selection in the Battalion is in Bold, then it's referring to the Keyword. See Deathmarch's Wight King, and Deathstench Drove's Corpse Carts on the page opposite in the battletome as reference examples. This means any unit with that keyword can be chosen.
If a required selection in the Battalion is not in bold, then its referring to a warscroll that has that name, or, a part of the name has that word; as vlad had shown with a screenshot from the core rules book:
Not simply typing Vampire Lord in bold, which would make it clear that both Vampire Lord, and Vampire Lord on Zombie Dragon are both valid options, prevents people from selecting the named vampires (Belladamma Volga, Lady Annika, Kritza, Radukar the Wolf, Radukar the Beast) Which seems to be the generally agreed upon way to read it.
I dont think there would be too many that would be obnoxious about the Battalion's requirements, except for the few that would insist on RAW it to deny the VLOZD purely because they don't want to face it.
But having them address it by making an errata that says to rewrite it as 2+ Vampire Lords and/or VLOZD for the sake of making it explicitly clear for anyone that wants to RAW it instead of RAI it, would be nice.
