Actually the tag chaos (warhammer) is listed under 'characters', but the imperium of man is under 'general'. Actually this make no sense at all, because both are factions in the game/universe, composed each other by many subfactions, and not characters.
so I propose to transfer te first tag to the 'general' section, implying him when a person tag slaanesh, khorne, nurgle, tzeentch and chaos space marine.
also the tag imperium of man should be implied when a person tag things such adeptus astartes, adepta sororitas etc
what do you think?
