I am Muslim Morocco who has gotten deeply involved in southern Germany and the Balkans having annexed a bunch of turf. The locals are unhappy about this and revolt a lot and I also keep getting attacked by my infidel neighbors. As of the moment I can't afford the cost of mass conversion, the $122 to put a missionary in Thrace was an eye-opener. Would it be better to vassal Hungary, Austria, etc., which I could do, and give them all my troublesome provinces or hold my Balkan conquests (and continue to get more) and wait until they core and I have the money to convert them? I have never had a large, off-religion vassal before so I don't know how reliable they are. Thanks.
