I just noticed that a sc2-legacy-of-the-void tag has been added:
However, some of this reasoning was based on the premise that Heart of the Swarm was an expansion and thus couldn't be played without Wings of Liberty, the base game. This has sinced changed, but that was one of our reasons at the time.
This is also true with Legacy of the Void: It is a standalone expansion.
I would've gone ahead and removed the use of sc2-legacy-of-the-void, but now I'm torn as to whether this is the correct course of action. Which is why I bring this to meta:
Should Legacy of the Void have it's own separate tag or not?
