I got a feeling one day CME will say the same thing and keep bumping up micro fees until finally they cost the same as e-minis. Ok maybe not exactly the same, but something like 80 cents per micro per side. They will raise prices slowly and use the boiling frog trick.
You can also use stop limit (works great for ES and MES), however for NQ and MNQ would suggest stop limit + 1 tick. from my personal experiences. 99% fill rate.
