Will you restrict player characters by faction in your campaign?
Something I've been thinking about is how to handle Horde and Alliance characters in the same party.
Back in older WoW, the faction divide was much stricter. Playing together across factions simply wasn't really a thing, and depending on when your campaign is set, having an Orc, Human, Forsaken, and Night Elf casually adventuring together could feel very strange from a lore perspective.
Modern WoW is obviously much more flexible about this, with the factions cooperating far more often and cross-faction gameplay becoming increasingly normal.
Of course, the era your campaign takes place in makes a huge difference. A campaign set during the Third War or early WoW might justify much stronger restrictions than one set in the current timeline.
I'm not sure yet how strict I'd want to be. Part of me likes preserving that faction identity and making Horde vs. Alliance actually matter, but at the same time I don't really want to tell someone they can't play the character they're excited about just because another player picked the opposite faction.
How are you planning to handle it in your campaign?
