I can’t be bothered reading this whole thread, but I’ve been playing a career mode as a fast bowler and I regularly get 2, 3, 4 and sometimes more wickets a game in 4 day games.
My general plan is have I think it’s the first preset field in the menu, but basically 3 slips with a gully, point and cover, mid on, mid off, square leg and and like a fine leg just in from the boundary. If the ball is swinging as a right armer bowling at off stump and taking it away trying to have the batsman hit into mid wicket and I’ll sometimes get an edge or a bowled. Trying to keep the length at the top of off stump or fuller with the odd back of a length. If the ball isn’t swinging much I move closer into the stumps and still bowl straight taking it away from the batsman with the same idea trying to get bowled or edges. I also use the broadcast camera as with the cameras that follow the bowler making you think you’re bowling a different line to what you are. I do the same thing to left handers around the wicket taking it away from close or starting really wide bringing it in to the stumps.
Works for me anyway
