Sounds like it’s more or less as easy to use on any difficulty level. Anyone playing on the top two difficulty levels should really expect a bit more challenge and timing than that!
I agree it would be good if you could perhaps fend a second defender if the timing was right and it wasn’t immediately after the first fend. Like if you fend off a midfield back and then run another 7-8 strides and then fend off the fullback. Obviously you’d have to have really good timing for the second one.
But overall the first one is far too easy and requires almost zero timing. That’s really only understandable for the bottom two difficulty levels.
