You don't require manual fielding to get stumpings - I've had several while online with things set to semi-auto. It might be a factor that manual fielding gives you a slight edge occasionally - but you're probably going to lose more wickets from not getting to chances then you would gain from getting one or two stumpings out of it.
The AI is just way too conservative about running between wickets after the fixes in the first patch for the huge amount of run outs. It's an area that needs some work.
