It would be really nice if TMW can add an condition type of "group size" (compatible of both party and raid).

I know there is a "instance size" condition type existing.

But noticed that it only works based on "instance", which doesn't work for raid groups in worlds / maps outside of an "instance".

For example 1, the "instance size" is still and always 0 (zero) when I'm in a raid group of world boss, like dooms-howl in "Arathi Highlands"

And example 2, it seems to be 0 (zero) when I'm in some big scenario, like Stromgarde warfront scenario.

If you want an aura to only activate if the group size is a certain number of people, you could use unit conditions for RaidX existing.

Going to go with @Jalopyy's solution as the official suggestion here. raid unitIDs are always sequential, so if raidN exists, your raid has N members.
