I suppose now most players won’t even know what this is let alone what it was used for…
You mean not used for…because back in the day, meeting stones sucked ass so hard that nobody touched ‘em. Ah, crappy-version-of-LFD-that-was-dungeon-specific-and-required-you-to-travel-to-the-stone-to-use, I miss you not.
They’re still useful when you get there before the warlock, or when you don’t have a warlock.
