Waterdeep Detective Agency (gestalt, level 15+)
I appreciate your opinion, but the following still remains:
This is a game designed around a detective agency of which my character would be the founder/leader. Thus, my character would select those who are members of that detective agency. Therefore, if I don't want multiple users of the same PrC, it can be assumed I would have weeded them out in the selection process for inclusion within the agency, given that he is seeking 'diversity' rather than 'duplication' of abilities brought to the table.
If this was a game designed around 'Bloodhounds', 'Justicars', 'Vigilantes', 'Nightsong Infiltrators', or 'Nightsong Enforcers', then I could see it being desirable to have members with the same PrC...but this isn't said game. If you want to see said game, feel free to make a GM request of your own.
Side Note: a GM request thread is a place to request a GM for a game that you, the requester, want to play in...and to some degree it is a place to express interest by other players to give a prospective GM an indication of whether interest exists for such a game or not. It is not a place for other prospective players to toss around their ideas of what the game should or shouldn't be. Just saying.
NOTE: Consecrated Harrier - hunts blasphemers, heretics, and those who betray or attack the church directly (this does not fit my view of this game concept)
Divine Oracle - although conceptually a candidate, it isn't one I'm interested in having presented in this game.
Nightsong Enforcer/Infiltrator - I've read both and don't see them as a fit for this game either.
