Yeah, I agree. Spreading my religion is simply too much of a bother - especially because IMO the Religious gameplay relating to conversion is super tedious. That's not VP's fault, it's base Civ, I just can't stand monotonously trudging Missionaries over to their destination. Now that it just isn't much use anyway, I find myself taking GoAC a lot just because it doesn't seem worth the play effort let alone the success effort. If I do found, I almost never build around intending to covert others.
There is an automate button on those bad little dudes, though. And it works pretty well.
