My bishop turned heretic and I banished him so I took over his Bishopric. Previous to this he was not granting me any levies or taxes because of his high favorability to the Pope. Now that I control the Bishopric as a Duke I get the "wrong government type" penalty but it seems to me to be better than before, I get some taxes and all the levies. This Bishopric is in my capital county so shouldn't I just hang on to it? What are the down sides of this? Thanks and I'm pretty new to CKII even though I've owned it a while, finally really get into it.
