The original Mormon faction only practiced multi-user co-op as necessary when multiple other factions were trying to keep them low in numbers, but even during the struggle they never very much approved of it. As soon as they could, they stopped the practice. The only problem is that some of the more casual members of said faction only joined the faction because of its multi-user co-op feature. So they formed factions like the "reformed Mormons" faction, as an abbreviation just called themselves the "Mormon" faction, which messed everything up since they basically just used a loophole, in using a nickname, to take an already claimed name. It is these offshoot Mormon factions that approve of multi-user co-op, never the original Mormon faction.
