The second door in the Church of Bane will not let people in unless Bane is their patron or attuned deity.
I think this should be changed to allow anyone who follows any of the other gods in the 'Bane pantheon' such as Loviatar, Mask, Hoar and a few others.
Currently we have multiple followers of Loviatar within our faction, and some have issues getting in as a result of this.
This also makes sense RP wise, because besides having them as members of the faction, there have always been shrines to multiple other gods within the church. As realistically most people would be some form of polytheist, I dont think it makes sense to force them to attune to Bane, as long as they follow one of his allies or servants.
