Here's the receipt for jihad exploit: Build multiple jihads and accumulate them and wait to lose a province. When you lose a province and unleash around 50 jihads on it. Building jihads is a out-of-the-balance good long term investment, since sooner or later you are going to lose a province, jihads require no support and when unleashed they deliver an army 4-5 times worth more gold than the 500 you payed to construct it. When the province is taken back, you have an army of doom that can conquer the world without problems. Furthermore as long as you have a province that was yours and belongs to somebody else you can continue to spawn jihads against it. What about limiting jihads to one at a time per faction, just as crusades? Is there any way I could make this modification on my own?
