Then there's the larger point that a trip or takedown doesn't just succeed or fail; defense typically means a sprawl or a clinch, often with plenty of shifting.
However there is no spawl or clinch in D&D. Greco and Folk wrestling have little support for D&D combat, period, considering the "kindly" squares-and-reach battlefield.
Therefore if you abstract out the "sprawl and clinch" into results and counters told by the result of a D20 during a combat round, you have the same amount of action and mechanical support without having to push through the Power System as simulation.
